摘　　要：高熵合金是近年来提出的一种新型合金材料,具有质量轻、强度高、刚性大、耐高温等特性,这些特性使高熵合金有望在航天材料领域得到应用。为抵抗太空环境的极端温度变化,通过高熵化的成分设计,高熵合金能够获得远高于传统超合金的高温屈服强度。由于存在孪晶变形等特殊变形机制,高熵合金显示出良好的低温韧性。在轻量化领域,可通过鸡尾酒效应使高熵合金获得合适的比强度。在空间防护领域,高熵合金的自修复效应能够有效抵抗辐照损伤。利用合理的成分设计还能够使高熵合金具备良好的耐磨、耐蚀性能。这些研究成果全方位显示出高熵合金在航天领域的应用上具有显著优势。High-entropy alloy(HEA)is a novel alloy proposed in recent years.Its characteristics of lightweight,high strength,high rigidity,and high-temperature resistance make HEA promising for applications in the field of aerospace materials.To resist extreme temperature changes in the space environment,HEA can achieve higher hightemperature yield strength than traditional superalloy through high-entropy composition design.HEA can also exhibit good toughness at low temperature due to special deformation mechanisms such as twinning deformation.In the field of lightweight materials,HEA can achieve suitable specific strength through the cocktail effect.In the field of space protection,the self-healing effect of HEA can effectively resist radiation damage.Reasonable composition design can also endow HEA with excellent wear and corrosion resistance.These performances comprehensively demonstrate the significant advantages of HEA in the aerospace field.
