Effects of Welding and rotational speeds on the Microstructure and Hardness of Friction Stir Welded Single-Phase BrassSajjad Emami,Tohid SaeidMaterials Engineering Faculty, Sahand University of Technology摘 要:This study focuses on the effects of rotational and welding speeds on the microstructure and hardness of joints in friction stir welded single......
reasons for the superior tensile properties of these joints. Key words: AZ61A magnesium alloy; friction stir welding; tensile properties; microhardness; microstructure 1 Introduction Structural... reactivity at high temperatures[4]. Friction stir welding (FSW) is capable of joining magnesium alloys without melting and thus it can eliminate problems related to the solidification. As FSW does......
, the process forces and heat input with varying parameters were studied. Helpful empirical models were developed in designing friction stir welding (FSW) tools and FSW welders. These models may be further helpful for making process parameter choice for this sort of alloy, defining welding program and control of process parameters by using computer numerical control friction stir welding welders. The results......
