A three dimensional heat transfer and material flow based model using experimentally measured thermo-physical properties has been developed for friction stir welding (FSW) of Cu-0.8Cr-0.1Zr alloy. CuCrZr alloy is a precipitation hardened copper alloy …
CuCrZr alloy (Cu-0.8wt-%Cr-0.1wt-%Zr) and 316L stainless steel (Fe-0.03wt-%C-16wt-%Cr-10wt-%Ni) plates were successfully friction stir lap welded resulting in significant mechanical mixing of the two matrix elements, Cu and Fe, in the stir zone. The …
Joining of high strength materials using friction stir welding (FSW) is difficult due to severe tool wear and change in the shape/size of the tool. However, quantitative understanding of tool wear during FSW of high melting point metallic materials …
