摘要 对4mm厚T4003铁素体不锈钢进行搅拌摩擦焊接工艺实验,研究焊接参数对接头组织特征、硬度分布及常温和低温冲击韧性的影响。结果表明:接头搅拌区和热力影响区由铁素体和马氏体双相组织构成;接头搅拌区组织沿试样厚度方向存在非均质性,且随转速的降低及焊接速率的增加越发显著;转速从150r/min增加至250r/min,前进侧热力影响区组织呈现小梯度过渡趋势,无明显变形拉长特征。焊缝硬度分布相对均匀,其最高硬度为290HV,约为母材的1.87倍。焊接参数和温度对接头的冲击吸收功有较大影响:常温(20℃)下,热影响区为母材的90%~92%,搅拌区为母材的85%~103%;低温(-20℃)下,热影响区为母材的87%~97%,搅拌区为母材的82%~95%,表明焊缝区仍具有较好强韧匹配。

Abstract:Friction stir welding(FSW) was performed for 4mm thick T4003 ferritic stainless steel(FSS) with different welding parameters. The effect of welding parameters on microstructure, hardness distribution, and impact toughness of FS-welded joints at room temperature and low temperature was investigated. The results show that the stir zone(SZ) and the thermo-mechanically affected zone (TMAZ) consist of duplex structure of ferrite and martensite. The SZ is heterogeneous along the thickness of the joint and this trend gets more obvious with the decrease of rotational speed and increase of welding speed. In the heat affected zone(HAZ) of the advancing side, the microstructure transits smoothly and no obvious characteristics of deformation and elongation as the rotational speed increases to 250r/min from 150r/min. The hardness distribution of the weld is relatively uniform and the maximum hardness is 290HV, approximately 1.87 times than that of the base material(BM). The welding parameters and temperature exert great effect on the impact absorbing energy of the welded joint. The impact absorbing energy of HAZ and SZ are up to 90%-92%, and 85%-103% of BM, respectively, at room temperature(20℃). While at low temperature(-20℃), the impact absorbing energy of HAZ and SZ reaches 87%-97%, and 82%-95% of BM, respectively. It shows that the weld zone still has better matching between strength and toughness.
