近年来,高熵合金凭借其新颖的设计理念和优异的各类物化性能成为金属结构材料领域的研究热点.随着轻量化合金设计理念的不断普及,"熵调控"的概念也被广泛应用于开发新型轻质合金.轻质高熵合金是基于合金轻量化设计的一类低密度的新型高熵合金,其开发与设计主要利用经验参数准则、相图计算以及第一性原理计算相结合的方法.其中,Al-Ti-V基轻质高熵合金凭借其优异的力学性能、良好的高温抗氧化性及耐腐蚀性等优点,受到了广泛关注.本文基于Al-Ti-V基轻质高熵合金的研究现状,从成分设计、制备方法、结构特征以及各类物化性能特点等方面进行了综述,并指出了Al-Ti-V基轻质高熵合金所面临的问题与挑战.
Research Progress of Al-Ti-V-based Lightweight High-Entropy Alloys
In recent years,high-entropy alloys(HEAs)have become the research hotspot in the field of metal structural materials because of their novel design concepts and excellent physicochemical properties.With the continuous popularization of lightweight alloy design concepts,the conception of"entropy regulation"has been widely used to develop new lightweight alloys.Lightweight HEAs(LHEAs)are a new type of low density HEAs based on lightweight alloy designs.Their development and design mainly combine the empirical parameter criteria,phase diagram calculations,and first-principles calculations.Al-Ti-V-based LHEAs attract much attention among various LHEAs due to their excellent mechanical properties,good high temperature oxidation resistance,and fine corrosion resistance.This paper summarized the research progress of Al-Ti-V-based LHEAs from the perspective of composition design,preparation methods,microstructures,and physicochemical properties.Meanwhile,the problems and challenges for Al-Ti-V-based LHEAs were also prospected.
