摘要

A novel TiVZr0.1Cr0.1 lightweight medium entropy alloy (MEA) with high specific strength and good strain hardening ability was developed in this study in order to satisfy the increased requirement for high performance light weight structure materials in the aerospace field. TiVZr0.1Cr0.1 MEA was rich in Ti and V elements, and consisted of body-centered cubic phase matrix, basket-like nanostructure in the grains, and Zr-rich irregular-shaped precipitates at the grain boundaries in the as-cast condition. The as-cast alloy exhibited a specific strength of 202 MPa/(g/cm3)) and a uniform elongation exceeding 4%. After annealing, Zr-rich precipitates at the grain-boundaries were re-dissolved and the uniform elongation of the alloy exceeds 6%.
