Abstract

A constitutive equation of rapid solidification (RS) powder metallurgy (P/M) magnesium alloy was constructed analytically from normalized strain rate-stress plots. Data related to RS P/M magnesium alloy showed deviation from those of conventional superplastic magnesium alloys; they indicated greater strength or lower strain rates than conventional superplastic magnesium alloys because the grains have a unique structure on superplastic flow. A constitutive equation for superplastic flow was developed using a metal matrix composite model.
