The effect of billet homogenization on final grain size and texture along with mechanical properties after indirect extrusion of a ZE20 magnesium (Mg) alloy were studied. As-cast and homogenized ZE20 billets were indirectly extruded at 454 degrees C. and an extrusion ratio of 25. Electron backscatter diffraction was used to characterize texture and grain size changes. Quasi-static mechanical testing at room temperature was conducted to determine effects on mechanical properties. The investigation of a thermal treatment on as-cast ZE20 prior to being extruded revealed an increase in ductility as well as a decrease in texture intensity of the homogenized billets.
