Analyses of Friction Stir Riveting Processes: A Review

Friction bit joining was developed by Mega Stir in which a consumable bit was used as the friction stir tool []. FBJ process mainly involves two steps, cutting and friction [ 33 – 35 ]. Initially, the consumable bit cuts through the top workpiece (Fig. 4(b) ), which is followed by a joining procedure where the friction heat results in heating the bit and work materials (Fig. 4(c) ).

Residual

Here we design a new magnesium sheet alloy-ZAXME11100 (Mg-1.0Zn-1.0Al-0.5Ca-0.4Mn-0.2Ce, wt. pct.) via CALPHAD (CALculation of PHAse Diagram) modeling and experimental validation. This new sheet alloy offers an excellent RT formability with a high Index Erichsen (I.E.) value of 7.8 mm in a solution-treated condition (T4), due to its weak and split more basal texture and fine grain structure.
