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.
