Microstructure and Mechanical Properties of X80 Pipeline Steel Joints by Friction Stir Welding Under
[期刊论文] 作者：G.M.Xie,R.H.Duan,P.Xue,Z.Y.Ma,H.L.Liu,Z.A.Luo,
来源：金属学报（英文版） 年份：2020
X80 pipeline steel plates were friction stir welded (FSW) under air,water,liquid CO2 + water,and liquid CO2 cooling conditions,producing defect-free welds.The microstructural evolution and mechanical properties of these FSW joints were stud......
Microstructural refinement mechanism and its effect on toughness in the nugget zone of high-strength
[期刊论文] 作者：R.H.Duan,G.M.Xie,P.Xue,Z.Y.Ma,Z.A.Luo,C.Wang,R.D.K.Misra,G.D.Wang,
来源：材料科学技术（英文版） 年份：2021
High-strength pipeline steel was subjected to friction stir welding (FSW) at rotation rates of 400-700 rpm,and the grain refinement mechanism of the nugget zone (NZ) was determined.The thermo-mechanical process during FSW in the NZ was simu......
