Characterization of tensile deformation in AZ91D Mg alloy castings
Abstract
AZ91 cast Mg alloy specimens in T4 and T6 tempers have been tested in tension. True stress -true plastic strain relationship has been characterized by evaluating the fits to four constitutive equations. Moreover, work hardening behavior in both tempers has been investigated and how well the four constitutive equation can model this behavior has been tested. The effects of temper and structural quality on tensile properties and work hardening are discussed in the paper.
