Compositional tuned non-equiatomic refractory high-entropy alloys are coveted materials as they achieve considerable plasticity through transformation-induced plasticity (TRIP) behavior. In this study, a novel Ti-rich Ti₆₀Mo₁₀V₁₀Cr₁₀Zr₁₀ refractory medium-entropy alloy (RMEA) was designed using FactSage. The plastic deformation of the alloy produced using vacuum arc remelting was investigated through a room-temperature compression test at different strain rates. A high strain-hardening rate and an m-value of 0.031 were observed in the Ti-rich Ti₆₀Mo₁₀V₁₀Cr₁₀Zr₁₀ RMEA. The dimple structures formed in BCC phases and TRIP-assisted deformation attribute to the strength and ductility trade-off in Ti-rich Ti₆₀Mo₁₀V₁₀Cr₁₀Zr₁₀ RMEA.

成分调整的非等原子耐火高熵合金是令人垂涎的材料，因为它们通过相变诱导塑性 (TRIP) 行为实现了相当大的塑性。在这项研究中，使用 FactSage 设计了一种新型的富钛 Ti ₆₀ Mo ₁₀ V ₁₀ Cr ₁₀ Zr ₁₀耐火中熵合金 (RMEA)。通过在不同应变率下的室温压缩试验研究了使用真空电弧重熔生产的合金的塑性变形。在富钛 Ti ₆₀ Mo ₁₀ V ₁₀ Cr ₁₀ Zr ₁₀中观察到高应变硬化速率和m值为 0.031RMEA。BCC 相中形成的凹坑结构和 TRIP 辅助变形归因于富钛 Ti ₆₀ Mo ₁₀ V ₁₀ Cr ₁₀ Zr ₁₀ RMEA的强度和延展性权衡。
