Effect of high temperature ECAP process on microstructure and mechanical properties of Ti-5553 alloy

Abstract

Abstract Excellent mechanical properties are the key to improve the erosion resistance of materials. Superplastic deformation process ECAP is a new heat treatment method which can refine grain size, improve the microstructure of materials and the comprehensive mechanical properties of materials. In this paper, the microstructure of Ti-5553 alloy treated by ECAP process and Ti-5553 alloy without ECAP process were observed, and the effect of high temperature ECAP process on the microstructure of Ti-5553 alloy was discussed. The effect of high temperature ECAP process on the mechanical properties of Ti-5553 alloy was studied by tensile test, and the effect of high temperature ECAP process on refining microstructure and improving mechanical properties of Ti-5553 alloy was discussed mechanism.
