Mechanical Behaviors and Microstructural Characteristics of TC11 Alloy during Hot Deformation

摘要

The mechanical behaviors and the microstructural characteristics of TC11 alloy with quenched martensite microstructure during hot compressive deformation were investigated. It shows that at various temperatures and strain rates, the stress-strain curves firstly exhibit strain hardening, then strain softening and finally reach the steady deformation state; in the meanwhile, the initial lamellar microstructure is tansformed into the equiaxed and uniform one through dynamic recrystallization.
