Dissimilar FSW

Atomically locked interfaces of metal (Aluminum) and polymer (Polypropylene) using mechanical friction

Joining different parts is one of the crucial components of designing/engineering of materials. Presently, the current energy efficient low weight automotive and aerospace components consist of a different class of materials, such as metals, …

Heat transfer modeling of dissimilar FSW of Al 6061/AZ31 using experimentally measured thermo-physical properties

A heat transfer numerical model is developed for friction stir welding of dissimilar materials Al 6061 and AZ31 alloy. Thermo-physical properties were experimentally determined for the stir zone and compared with the base alloys. Experimentally …

Towards attaining dissimilar lap joint of CuCrZr alloy and 316L stainless steel using friction stir welding

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 …
