    Yi-lin YANG, Xun LU, Wei-wei WANG, Zhi-jie JIANG. Preparation and Characterization of Thermally Reversible Self-healing Polyurethane Elastomer[J]. Journal of Materials Engineering, 2017, 45(8): 1-8.

    In order to investigate the structure and property relationships of intrinsic self-healing polyurethane and balance the seemly contradictory forces between its self-healing efficiency and mechanical strength, the reversible disulfide bonds were introduced into polyester-polyurethane by taking hexamethylene diisocyanate (HDI) trimers as the cross-linker and 4, 4-diamino diphenyl disulfide as the chain-extender. The results show that the optimal self-healing elastomer exhibits a tensile strength of 7.7MPa and a maximum self-healing efficiency of 97.4% at 60℃after 24 hours, whereas the common elastomer synthesized without disulfide bonds (via H-bonding interactions) only exhibits a tensile strength of 9.3MPa and a maximum self-healing efficiency of 58.0% under the same condition, indicating that the existence of disulfide bonds helps to increase the self-healing efficiency by 67.9%. The prepared elastomer is found to have multi time self-healing capabilities and the second time self-healing efficiency is 62.3%.

    The resistance and the surface morphology of the graphene films were studied after atomic oxygen exposure. The graphene films can be etched away during atomic oxygen exposure, the resistance of graphene films decreases at first and then increases. It shows that the adsorption of oxygen atom may play an important role in the change of the resistance of graphene films at the beginning of the exposure and then the change of the resistance conforms to the law of resistance. The atomic oxygen erosion rate which is about 1.2×10-25cm3/atom to 1.3×10-25cm3/atom can be obtained. A kind of new atomic oxygen detector was put forward based on the relationship between the resistance of graphene films and atomic oxygen fluence.

    Jia-hui QU, Jin-lei CHEN, Hong LI, Wen-jie ZHANG. xLa-3%In-TiO2 Photocatalytic Material Prepared by Sol-gel Method[J]. Journal of Materials Engineering, 2017, 45(8): 14-18.

    A sol-gel method was applied to prepare xLa-3%(mole fraction, the same below)In-TiO2 photocatalytic materials, which were characterized by XRD, SEM, surface area, and pore size distribution measures. Photocatalytic activity of the materials was also evaluated. The results show that the materials are in tetragonal anatase structure. Crystalline size of TiO2 decreases after doping La and In. In3+ and La3+ exist in TiO2 crystal lattice by substituting Ti4+. La doping results in enlarging surface area and shrinking pore size. Pore size of xLa-3%In-TiO2 is mainly in the range of 1.5-10nm. Doping of La obviously leads to enhanced photocatalytic activity. Photocatalytic rate constants of methyl orange are 0.061min-1 and 0.029min-1 on 0.3%La-3%In-TiO2 and 3%In-TiO2, respectively. The chromogenic groups in methyl orange molecules can be degraded during photocatalytic process.

    Jun-jie XIONG, Hong YAN. In-situ Al3Ti/ADC12 Composites Synthesized from Al-Ti System[J]. Journal of Materials Engineering, 2017, 45(8): 30-37.

    Aluminum matrix composites reinforced by in-situ Al3Ti particles were successfully synthesized from an Al-Ti system via a direct melt reaction. The influences of Ti additions, ultrasonic time and power on the microstructure and mechanical property of composites were systematically investigated. The results show that the Al3Ti particles are refined obviously and the distribution also becomes more uniform with the increase of ultrasonic power. Meanwhile, the addition of Ti refines the α-Al dendrite phases in the matrix, which gradually changes from the original coarse to fine branch crystals, rose-like or nearly spherical. However, results also show that the size of Al3Ti particles decreases to a minimum value and then increases with the increase of ultrasonic time. The trends of the mechanical properties are consistent with the microstructures of the Al3Ti/ADC12 composites. The optimum parameters of the composite are 3%Ti (mass fraction) content, 1.5kW ultrasonic power, 20kHz ultrasonic frequency and 6min ultrasonic time. Accordingly, the tensile strength and elongation of the composite synthesized reach to 247.34MPa and 2.31% respectively, increasing by 21.3% and 50.0% compared with the unmodified alloy.

    Hong-mei CHEN, Yu-lin ZHU, Song WANG. Effect of Post Heat Treatment on Microstructure and Properties of Cf/ZrC Composites[J]. Journal of Materials Engineering, 2017, 45(8): 43-48.

    Carbon fiber reinforced zirconium carbide ceramic matrix composites (Cf/ZrC) were fabricated by reactive melt infiltration at relative low temperature, C/C composites as substrate, Zr2Cu alloy as infiltrator. Effect of post heat treatment on microstructure and properties of Cf/ZrC composites was investigated. The results show that after different temperature heat treatments at 1400-2200℃, the density of the composites decreases, and the porosity increases. During post heat treating, the residual copper rich melt in the composites evaporates, the volume fraction of ZrC matrix increases and the damage to the microstructure of ZrC matrix occurs. The mechanical properties of the composite decrease after post heat treatments. The flexural strength retention rate of the composites is only 52.3%, when the heat treatment temperature reaches 2200℃.

    The methyl acryloyloxy propyl silsesquioxane(MAP-POSS) was prepared by hydrolysis condensation of KH-570, and composing free radical-cationic hybrid UV curing system with the unsaturated epoxy resin. The changes of characteristic absorption peak in the curing process was characterized by using infrared spectroscopy (FT-IR), and the influence of MAP-POSS content on the surface water contact angle, silicon elements distribution, mechanical properties and thermal performance of UV-cured film was investigated. The results show that with the addition of MAP-POSS the crosslinking degree, hydrophobicity, thermal stability and glass transition temperature(Tg) of the film are improved. When the content of MAP-POSS is 12% (mass fraction, the same below), Tg is increased by 16.9℃. When the MAP-POSS content is 15%, the water contact angle of film is increased from 58.0° to 94.2°. The impact strength is improved firstly and then decreased with the addition of MAP-POSS.

    The toughened composite was prepared by the domestic high strength medium modulus carbon fiber (CCF800H) reinforced epoxy resin matrix. The influence of different content of toughening thermoplastic within epoxies on the mode-Ⅰ interlaminar fracture toughness (GⅠC) of composites was investigated. The results show the initial strain energy release rate (GⅠC-init) and the propagational strain energy release rate (GⅠC-prop) of composites improve remarkably with the increasing of content of toughening thermoplastics within epoxy matrix. In the case of mass fraction of thermoplastic is greater than 20% of epoxy, the toughening aromatic polyetherimide particle can be concentrated on the interlayer of composite to form the high interlaminar toughness zone. The interlaminar toughened structure constituted by 'continuous phase' and 'dispersion phase' is fabricated on the interlayer of composite.

    Xin-jian CAO, Jian-feng JIN, Jing-yi CAO, Ya-ping ZONG. Wear Resistance of Iron Matrix Composites Reinforced by Mixed-type Particles[J]. Journal of Materials Engineering, 2017, 45(8): 62-67.

    Ceramic particles reinforced iron matrix composites were prepared by the dynamic temperature resistant hot press technology. The wear resistance of the iron matrix composites reinforced by monolithic particles (SiC, TiC, TiN) and hybrid particles mixture (TiC+TiN, SiC+TiN, SiC+TiC) under high volume fraction of 25%, 30% and 35% were investigated. The results show that when using monolithic particle as reinforcement, the wear resistance of the TiNp/Fe composite is the best among the three monolithic composites, the TiCP/Fe is the second and the SiCP/Fe is the worst. The wear resistance of (TiC+TiN)P/Fe is better than that of the composites reinforced by corresponding monolithic particles, which represents the great effect of hybrid strengthening. When the volume fraction of particles is 30%, the wear resistance of the (TiC+TiN)P/Fe composite increases the most and the wear loss decreases by 51.9% and 44.1% than that of the TiCP/Fe and TiNp/Fe, respectively. However, the wear resistance of (SiC+TiC)P/Fe and (SiC+TiN)P/Fe composites are between that of the two corresponding monolithic composites. The microstructure of worn surfaces shows that the wear mechanism of the (TiC+TiN)P/Fe composite is abrasive wear, while that of the (SiC+TiN)P/Fe and (SiC+TiC)P/Fe are fatigue and abrasive wear.

    Ya-jun CHEN, Xian-chao WANG, Fu-sheng WANG, Bo LIU. Fatigue Behavior of 2A12 Aluminum Alloy Under Multiaxial Loading[J]. Journal of Materials Engineering, 2017, 45(8): 68-75.

    The multiaxial fatigue behavior of 2A12 aluminum alloy was studied with SDN100/1000 electro-hydraulic servo tension-torsion fatigue tester under multiple variables, and the failure mechanism was investigated by scanning electron microscopy (SEM). The results show that under the loading condition of equivalent stress, the fatigue life decreases with the increase of phase angle. For the phase angle 0°, some special features can be observed in the crack initial zone, such as the tire pattern, fishbone pattern and stalactite pattern. There are secondary cracks and vague fatigue striations in the crack propagation zone; the multiaxial fatigue life decreases with the change of mean stress for tension or torsion. Some white flocculent oxides can be found in the crack initiation zone, and secondary crack as well as shear-type elongated dimples in the instantaneous fracture zone; facing different loading waveforms, the multiaxial life of sine wave is the longest, triangle wave in the second place, and the square wave is the shortest, under the loading condition of equivalent stress, square wave leads to the maximum structural energy dissipation. Under the low and high two step loading, 2A12 shows training effect.

    Ping FU, Xu LIU, Qing-song DAI, Jia-qi ZHANG, Yun-lai DENG. Modification of Flow Stress Curves and Constitutive Equations During Hot Compression Deformation of 5083 Aluminum Alloy[J]. Journal of Materials Engineering, 2017, 45(8): 76-82.

    The flow stress behavior of 5083 aluminum alloy was investigated under hot compression deformation at 523-723K, strain rates of 0.01-10s-1 and true strains of 0-0.7 with Gleeble-3800 thermal simulator. Based on the heat transfer effect on alloy deformation heat effect, the flow stress curves were corrected. The results show that influence of heat conduction can not be neglected and becomes more obvious with the increase of true strain. The corrected flow stress has little influence on the peak stress, but the steady flow stress softening trends to be diminished to some degree. The flow stress can be predicted by the Zener-Hollomon parameters in the constitutive equation. The corrected measured value exhibits a good agreement with the flow stress predicted by the constitutive equation, and the average relative error is only 5.21%.

    The Fe30Mn5Al alloy was oxidized at 800℃ in air for 160h, the oxidation-induced layer about 15μm thick near the scale-metal interface was induced to transform to ferrite and become enriched in Fe and depletion in Mn. The effect of the oxidation-induced Mn depletion layer on the electrochemical corrosion behavior of Fe30Mn5Al alloy was evaluated. The results show that in 1mol·L-1 Na2SO4 solution, the anodic polarization curve of the Mn depletion layer exhibits self-passivation, compared with Fe30Mn5Al austenitic alloy, and the corrosion potential Evs SCE is increased to -130mV from -750mV and the passive current density ip is decreased to 29μA/cm2 from 310μA/cm2. The electrochemical impedance spectroscopy(EIS) of the Mn depletion layer has the larger diameter of capacitive arc, the higher impedance modulus|Z|, and the wider phase degree range, and the fitted polarization resistant Rt is increased to 9.9kΩ·cm2 from 2.7kΩ·cm2 by using an equivalent electric circuit of Rs-(Rt//CPE). The high insulation of the Mn depletion layer leads to an improved corrosion resistance of Fe30Mn5Al austenitic alloy.

    Zhi-qiang YANG, Zheng-dong LIU, Xi-kou HE, Ning LIU. Hot Deformation Behavior of SA508Gr.4N Steel for Reactor Pressure Vessels[J]. Journal of Materials Engineering, 2017, 45(8): 88-95.

    The high-temperature plastic deformation and dynamic recrystallization behavior of SA508Gr.4N steel were investigated through hot deformation tests in a Gleeble1500D thermal mechanical simulator. The compression tests were performed in the temperature range of 1050-1250℃ and the strain rate range of 0.001-0.1s-1 with true strain of 0.16. The results show that from the high-temperature true stress-strain curves of the SA508Gr.4N steel, the main feature is dynamic recrystallization, and the peak stress increases with the decrease of deformation temperature or the increase of strain rate, indicating the experimental steel is temperature and strain rate sensitive material. The constitutive equation for SA508Gr.4N steel is established on the basis of the true stress-strain curves, and exhibits the characteristics of the high-temperature flow behavior quite well, while the activation energy of the steel is determined to be 383.862kJ/mol. Furthermore, an inflection point is found in the θ-σ curve, while the -dθ/dσ-σ curve shows a minimum value. The critical strain increases with increasing strain rate and decreasing deformation temperature. A linear relationship between critical strain (εc) and peak strain (εp) is found and could be expressed as εc/εp=0.517. The predicted model of critical strain could be described as εc=8.57×10-4Z0.148.

    Based on an as-serviced 25Cr35Ni type steel, the high temperature property evaluation using stress relaxation test(SRT) method and residual life prediction were studied. The results show that creep rupture property decreases because of the formation of network carbides along grain boundaries and coarsening of secondary carbides in the austenitic matrix. Based on the relationship of stress relaxation strain rate curves obtained at different temperatures, and the extrapolation equation of stress relaxation rate-rupture time, it is capable to perform residual life evaluation by combining SRT data and a small amount of creep rupture test(CRT). Good agreement is observed for predicting results performed by current method and traditional method.

    Jun DU, Xiao-ying ZHU, Hong-mei WANG. Nano Multilayer Structure Toughening of Hard Coatings-Method, Mechanism and Application[J]. Journal of Materials Engineering, 2017, 45(8): 102-114.

    The toughening of hard coating is becoming very important from engineering point of view. Nano multilayer structure is one of the effective way towards toughening. A comprehensive discussion on composition and toughening mechanism of structure toughening was presented. The effect of period, period ratio and microstructure on toughening, and the application of multilayer structure toughening in wear and erosion were also discussed. Micro-crack deflection is the main mechanism of toughening, but the more interface, the more initiation of cracks, results in spalling failure in case of little interfacial toughness. It can be concluded that interface quality rather quantity dominates toughening effect. In order to show the advantage of nano multilayer film, a good interfacial toughness must be obtained, and the blocking of the propagation of micro cracks should be considered from fracture mechanics point of view.
