Stress relaxation of AZ31 alloy using high energy diffraction microscopy
AZ31 is a commercial Mg-3%Al-1%Zn ternary alloy with good specific strength, but relatively limited room temperature formability -- a consequence of marked difference in strength of slip systems in this hcp alloy. Tensile test is the traditional method to study the kinetics of individual slip/twin …
