Friction Stir Channeling Tool Design for Better Material Flow and Channel Strength

This research investigates the impact of shoulder-workpiece separation on the friction stir channeling of copper, comparing two distinct tool designs. One design includes a clearance between the tool shoulder and workpiece; while, the other utilizes …

Microstructure and fatigue crack growth behavior of heat-treated electron beam melted Ti-6Al-4V alloy

The effect of post-deposition heat treatment on microstructure and fatigue crack growth has been analyzed for electron beam melted Ti-6Al-4V plates. Samples have been heat-treated at temperatures of 950◦C, and subsequently cooled at different cooling …

Friction stir welding of additively manufactured Ti-6Al-4V: Microstructure and mechanical properties

Additive manufacturing of titanium alloy Ti-6Al-4V has significantly increased over the past few years, primarily due to its broad application over the conventional manufacturing process for complex and near net shape production. However, …

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 …
