摘要

与传统合金相比，具有多组分元素的高熵合金（HEAs）具有许多优越的性能，因此引起了人们的极大兴趣。这些特性包括显著的能量释放、显著的断裂韧性和高强度，使其成为有希望的含能结构材料（esm）。本文综述了tizr基HEAs、tinb基HEAs和w基HEA在动态冲击下的能量释放机理和力学行为，包括能量释放速度阈值、腔室准静压曲线、能量释放效率、界面反应和“自锐化”等。并对其能量释放和力学行为提出了未来的研究方向。

Prospects of energy release and mechanical behavior of reactive high-entropy alloys

High-entropy alloys (HEAs) with multi-component elements have attracted significant interest since they exhibit numerous superior properties compared to traditional ones. These properties include significant energy release, remarkable fracture toughness, and high strength, making them promising candidates as energetic structural materials (ESMs). This paper summarizes the energy release mechanisms under dynamic impact and the mechanical behavior of TiZr-based HEAs, TiNb-based HEAs, and W-based HEA, including velocity threshold for energy release, chamber quasi-static pressure curve, energy release efficiency, interface reactions, and "self-sharpening". In addition, we propose future research directions for their energy release and mechanical behavior.
