论文摘要
最近，包含至少五个主要元素的高渗透合金和陶瓷最近对各种机械和功能应用受到了极大的关注。与工程材料的正常功能相比，严重的塑性变形（SPD）的应用，特别是高压扭转（HPT）方法，结合了Calphad和第一原理计算，从而发展了许多具有优质特性的高功能高渗透材料。本文回顾了SPD在开发超功能高渗透材料中应用的最新进展。这些超功能的特性包括（i）与高渗透合金中陶瓷硬度相当的超高硬度水平，（ii）高屈服强度和高渗透合金中良好的氢耐耐药性； （iii）高强度，低弹性模量和高渗透合金中的高生物相容性，（iv）高渗透氢化物中的快速和可逆氢储存，（v）光伏性能，并在高渗透半导体（VI）光电氧和光电氧气生产的高渗透氧和光层上的光电上产生高氧气和水中的高氧化层上的高氧气和水中的高氧化层，并在水中产生高氧气，并且水中的水分覆盖高氧气，并在水上覆盖高氧气，并在水上覆盖高氧（vii）高渗透陶瓷上的CO2光摄取。这些发现引入了SPD，不仅是一种加工工具，可以改善现有高渗透材料的性质，而且还作为一种合成工具，可以与常规工程材料相比，生产具有出色特性的新型高渗透材料。
High-entropy alloys and ceramics containing at least five principal elements have recently received high attention for various mechanical and functional applications. The application of severe plastic deformation (SPD), particularly the high-pressure torsion (HPT) method, combined with the CALPHAD and first-principles calculations resulted in the development of numerous superfunctional high-entropy materials with superior properties compared to the normal functions of engineering materials. This article reviews the recent advances in the application of SPD to developing superfunctional high-entropy materials. These superfunctional properties include (i) ultrahigh hardness levels comparable to the hardness of ceramics in high-entropy alloys, (ii) high yield strength and good hydrogen embrittlement resistance in high-entropy alloys; (iii) high strength, low elastic modulus, and high biocompatibility in high-entropy alloys, (iv) fast and reversible hydrogen storage in high-entropy hydrides, (v) photovoltaic performance and photocurrent generation on high-entropy semiconductors, (vi) photocatalytic oxygen and hydrogen production from water splitting on high-entropy oxides and oxynitrides, and (vii) CO2 photoreduction on high-entropy ceramics. These findings introduce SPD as not only a processing tool to improve the properties of existing high-entropy materials but also as a synthesis tool to produce novel high-entropy materials with superior properties compared with conventional engineering materials.
