摘要: 依据等原子比和高混合熵的合金设计理念制备TixCrFeCoNiAl 多组元固溶体合金系, 研究了该合金系的室温压缩力学性能和显微硬度, 并对其强化机制进行了探讨. 结果表明: TixCrFeCoNiAl合金系具有很高的强度和优异的综合力学性能, 其中T1合金的屈服强度、断裂强度和塑性变形量分别高达2.259 GPa、3.135 GPa和23.22%; 该合金系具有很高的显微硬度, 且随着Ti含量的提高而近线性地提高, T3合金的显微硬度达到HV768; 固溶强化机制、 纳米相弥散强化机制和晶格畸变效应使合金系具有很高的强度和显微硬度.

Abstract:TixCrFeCoNiAl (x: molar ratio, x=0,0.5,1,1.5, denoted by T0、T1、T2 and T3, respectively) alloys, which were designed using the strategy of equal-atomic ratio and high entropy, were studied on its mechanical properties and strengthening mechanism. All the four alloys possess fairly high strength and micro-hardness. Among them, both T0 and T1 alloys have excellent comprehensive mechanical properties. Particularly for T1 alloy, the yield stress, fracture strength and plastic strain are as high as 2.259GPa, 3.135GPa and 23.22% respectively, which are even superior to most of the high-strength alloys like bulk metallic glasses. The super-high strength the four alloys should be attributed to the effective multi-strengthening mechanism like solid solution strengthening, nano-phase dispersion strengthening and lattice distortion effects, etc.
