| Abstract Scope |
Additive friction stir deposition of AZ31BMg alloy was explored using MELD technique. The process involved a hollow steel tool consisting of a coaxial 1cm2 square cavity through which bar stock of AZ31BMg was pushed against the base plate. The tool was rotated at 400rpm and translated with the velocities from 4.2 to 6.3mm/s to deposit 5 layers of dimensions 140x40x1mm3. Thermocouples embedded within the base plate monitored temperature evolution as the deposition was carried out. Vital process attributes such as tool torque and actuator force were monitored using onboard sensors and converted to overall heat input. Deposition temperatures and strain rates were estimated using process attributes. The deposited material evolved a marginally refined microstructure compared to the feed stock consisting of α-Mg phase with predominantly basal texture. The refinement in microstructure was reflected in a minor improvement in the Vickers hardness of the deposits compared to the feedstock |
