Hui Weijun, Li Rong, Weng Yuqing. Effect of Rare Earth on the Fracture Toughness and Ductility of l8Ni(350) Maraging Steel[J]. Journal of Materials Engineering, 1996, 0(2): 19-23.
By measuring in the conventional mechaical properties and examining qualitatively and quantitatively inclusions of the RE-treated and non-RE-treated l8Ni(350)maraging steel,it was found that the toughness and ductility can be improved by suitable lanthanum addition.Affected by the particular chemical composition of maraging steel and other reasons,the improvenment of toughness and ductility of suitable La-treated maraging steel is not significant.
Song Xiping, Meng Weiru, Shao Tanhua, Wang Shiyua, Liu Xiaofang. A Study of the Formation of Weld Microstructure in Inertia Friction Welding of Ti-6Al-4V Alloy[J]. Journal of Materials Engineering, 1996, 0(2): 24-26.
The formation of weld microstructure in inertia friction welding by was studied mans of microscope,SEM and TEM.The results show that microstructure of weld zone greatly changes in the radial direction. The centre of joint is characterized by fine equiaxial grains.The flashing is by lamellar structure.A“V”shape weld zone is formed from the centre of joint to the flashing.
Huang Hui, Zheng Ziqiao, Yin Dengfeng. The Effect of Small Additions of Silver on the Tensile Property and Microstructure of Al-Li(CP276)Alloy[J]. Journal of Materials Engineering, 1996, 0(2): 27-29.
The effect of change in Ag contents on the tensile property and ageing microstructure of Al-Li (CP 276)alloy has been studied.Adding 0.11wt%Ag to the alloy promote the precipitation of T1 phase and improve the peak strength.The GP zones containing Ag and Mg appear in the earlier ageing stage in the alloy containing 0.38wt% Ag,decreasing the solubility of Cu in the alloy,preventing the precipitation of T1 phase and reducing the strength;in the further ageing stage,GP zones are dissolved,T1 phase precipitated enmously and the peak strength is improved.
