Abstract

Abstract

This paper performs thermal compression studies on GH4065A samples from a sample disk that is obtained from an industrial plant and has undergone VIM+ESR+VAR and homogenization. This study reveals the impact of thermal compression parameters such as deformation temperature, strain rate and engineering strain on the flow stress of GH4065A, and constructs constitutive equations of GH4065A at the 50% engineering strain. Based on experimental data, the thermal processing map and instability criterion map of GH4065A are proposed, by which the stable processing zones of GH4065A can be identified. This paper also studies the microstructure evolution of GH4065A, and the results reveal the precipitation range of γ’ phase, non-recrystallization processing range, partial recrystallization processing range, and full recrystallization processing range of GH4065A, by which the recrystallization map is proposed.
