Magnesium Alloy Az31b

The Friction Stir welding is a solid state welding invented in the year 1991.This welding technique is highly energy efficient, eco-friendly in joining the high strength aerospace aluminums alloys and its other alloys which are not able to weld by the conventional fusion welding process. Initially FSW is use to weld aluminums alloys and gradually it applies to all form of metals and alloys. In this review article the current state of understanding and development of FSW with respect to Magnesium alloys AZ 31 B is addressed. And particular emphasis is given to the effect of FSW process parameters on the mechanical properties, corrosion behavior and microstructure evolution. At this stage there is wide gap in understanding the mechanism of dissimilar Magnesium welds on microstructure evolution and microstructure property relationships with respect to FSW and Submersible FSW process.

High Manganese Austenitic Steel

This work addresses the influence of deformation temperature in a range from −40°C to 200°C on the microstructure evolution and mechanical properties of a low-carbon high-manganese austenitic steel. The temperature range was chosen to cope at the time during sheet processing or car crash events. Experimental results show that yield stress and ultimate tensile strength gradually deteriorate with an increase in the tensile testing temperature. The dominant mechanism responsible for the strain hardening of steel changes as a function of deformation temperature, which is related to stacking fault energy (SFE) changes. When the deformation temperature rises, twinning decreases while a role of dislocation slip increases.
