2ZrNbV（at%）高熵合金。研究了固溶體相的穩(wěn)定性，以及金屬間化合物V2Zr析出對拉伸性能的改善。結(jié)果表明：合金在900 ℃以上是穩(wěn)定單一均質(zhì)固溶體相，低于此溫度時，Laves相V2Zr 容易在基體中析出。單一固溶相的不穩(wěn)定性可用于強化Ti2ZrNbV高熵合金。經(jīng)過固溶和時效處理后，合金的拉伸屈服強度可達1145 MPa，塑性伸長率為8.3%。;A bcc-structured Ti2ZrNbV (at%) high entropy alloy was prepared by vacuum arc melting. The stability of the solid solution phase was studied, and the improvement of tensile property via V2Zr phase precipitation was investigated. The results show that the homogenous solid solution phase is stable above 900 °C, and Laves phase V2Zr easily precipitates below this temperature. The instability of the solid solution phase can be used for enhancing the Ti2ZrNbV alloy. After solid solution and aging treatment, the tensile yield strength of the alloy can reach 1145 MPa with a promising elongation of 8.3%."/>
