研究了单相{Gamma}-Ti{sub47}Al{sub51}Mn{sub2}合金的多晶样品在较宽的温度范围(120-1270K)下的力学性能。在外加应变率试验中测量了流动应力和加工硬化率，同时考察了应力的应变率敏感性和这些参数的应力相关性，结果表明，所研究的温度域可分为三个区域，对应于不同的变形机制。结果与文献中的数据进行了比较，发现与作者以前报道的位错结构和位错运动机制很好地吻合。
The mechanical properties of polycrystalline samples of the single phase {gamma}-Ti{sub 47}Al{sub 51}Mn{sub 2} alloy have been studied during compression tests in a wide range of temperatures (120--1,270 K). The flow stress and the work hardening rate are measured during imposed strain rate tests, while the strain rate sensitivity of the stress is examined and stress dependence of these parameters, it is shown that the investigated temperature domain can be divided into three regimes corresponding to different deformation mechanisms. The results are compared to the data available in the literature and are found to be in good agreement with the dislocation structures and dislocation motion mechanisms that the authors have previously reported.
