SUPERPLASTIC DEFORMATION BEHAVIOR OF 01420 ALLOY

LI Xianmi

Abstract

The thermomechanical processing and superplastic deformation behavior of 01420 alloy have been investigated. A new thermomechanical processing, i.e. solution treatment, cooling in furnace, rolling at 300℃, recrystallization and ageing was adopted. The average grain size of 01420 alloy treated by this method was 8~10μm. The elongation of superplastic deformation reached 950% and m value 0.78, best result for this alloy was obtained.
