Carefully controlling the texture, grain size and the precipitate size and volume fraction in magnesium alloys yields improvement in the strength and elongation and improve the compressive to tensile yield stress ratio. It has been demonstrated that the Shear Assisted Processing and Extrusion (ShAPETM) technique can help achieve the same in magnesium alloys in a cost effective way. In the current work 50 mm ZK60 alloy tubes with 1.5 mm wall thickness were extruded using the ShAPETM process and were subjected to heat treatments ranging from 150oC to 400oC for up to 100 hrs. The formed structures were later evaluated for their strength and the final microstructure characterization was performed to determine the grain size, texture (using EBSD) and phases formed (using TEM and atom probe tomography).
