tixcrfeconial多组元固溶体合金系的力学性能及其强化机制
Keywords: 金属材料,固溶体,力学性能
Abstract:
？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2.259gpa、3.135gpa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.
