高熵合金（HEAs）在结构稳定性方面表现出优异的耐辐照性。然而，有限的知识已经提供了离子辐照后的体心立方结构的HEAs的力学性能的趋势。在这项研究中，HfNbZrTi与3 MeV的C离子辐照的力学性能的演变进行了研究的基础上微柱压缩试验。屈服强度几乎线性增加，从974至2068 MPa，增加辐照剂量高达0.98 dpa。力学性能和微观组织变化之间的相关性与Δ δ y= α MG B（ND）1 2的预测一致，表明与常规合金相似的强化机制。尽管如此，在这种合金的辐照强化效果是不太明显的低剂量制度，和饱和推迟，与不锈钢和3D金属高熵合金与面心立方结构，表现出有前途的耐辐照性有关的机械性能。
High entropy alloys (HEAs) have exhibited excellent irradiation resistance regarding structure stability. However, limited knowledge has been available on the tendency of mechanical properties of HEAs with body-centered cubic structures after ion irradiation. In this study, the evolution of mechanical properties of the HfNbZrTi irradiated with 3 MeV C ions is studied based on micropillar compression tests. The yield strength increases almost linearly from 974 to 2068 MPa with increasing irradiation doses up to 0.98 dpa. The correlation between the mechanical and microstructural changes agrees well with the prediction of Δ δ y= α M G b (N D) 1 2, indicating a similar strengthening mechanism with conventional alloys. Nonetheless, the irradiation strengthening effect in this alloy is less pronounced in the low dose regime, and the saturation is postponed, compared with the stainless steel and the 3d metal high entropy alloys with face-centered cubic structures, exhibiting promising irradiation resistance regarding mechanical properties.
