摘要

设计了一种新型的Hf30.3Nb10Ta20.3Ti30.3Al9.0耐火多主元素合金（RMPEA），采用短时间退火工艺，获得了较好的强度和塑性结合，超越了以往报道的大多数RMPEA。弯曲的非螺旋位错是主要的塑性变形机制，而微带诱导的塑性效应有助于持续的应变硬化能力。

HfNbTaTiAl refractory multi-principal element alloy with excellent tensile properties at room temperature

A novel Hf_30.3Nb₁₀Ta_20.3Ti_30.3Al_9.0 refractory multi-principal element alloy (RMPEA) was designed with short-time annealing to achieve excellent combination of strength and ductility, surpassing most of the previously reported RMPEAs. The curved non-screw dislocations serve as the main plastic deformation mechanism, while the microband induced plasticity effect contributes to the sustained strain-hardening ability.
