Abstract

Under research supported by US Army, a process of alternate biaxial reverse corrugation (ABRC) was explored to impart severe plastic deformation to ZK60 Mg alloy. This process had previously being utilized to strengthen AZ31 Mg and reported elsewhere [1]. The present results with ZK60 alloy exhibit higher strength (>3 50 MPa), and retention of adequate ductility (> 7% tensile elongation). The enhanced strength levels are believed to be influenced by precipitates found in this alloy not existing in AZ31 alloy, in addition to grain size strengthening produced by grain size < 1 μm. Partial depth penetration into alloy plate from the top and bottom surfaces by friction stir process (FSP) was also examined to cause a different form of grain refinement. The strengthening effect and ductility in this case are found to be comparable to ABRC processed material.
