Abstract

Features of the microstructure of the shape-memory Ti–51 at %Ni alloy subjected to aging at different temperatures are studied. Along with metallographic analysis performed by optical and electron microscopy and X-ray diffraction analysis, room-temperature tensile tests of the mechanical properties are performed. The alloy in the aged state is found to be characterized by the high level of mechanical properties (the ultimate strength is up to 1200 MPa and the relative elongation, 35%) owing to the highly dispersed homogeneous decomposition and the simultaneous strengthening and increase in the plasticity as a result of strain-induced martensitic transformation.

经过热处理的老化形状记忆 Ti49Ni51 合金的分解特征和力学性能
摘要 研究了在不同温度下进行时效处理的镍含量为%的形状记忆 Ti-51 合金的微观结构特征。除了用光学和电子显微镜进行金相分析以及 X 射线衍射分析外,还进行了室温拉伸力学性能测试。研究发现,由于高度分散的均匀分解以及应变诱导的马氏体转变导致的塑性增强和提高,该合金在老化状态下具有较高的机械性能(极限强度高达 1200 兆帕,相对伸长率为 35%)。

期刊介绍: The Physics of Metals and Metallography (Fizika metallov i metallovedenie) was founded in 1955 by the USSR Academy of Sciences. Its scientific profile involves the theory of metals and metal alloys, their electrical and magnetic properties, as well as their structure, phase transformations, and principal mechanical properties. The journal also publishes scientific reviews and papers written by experts involved in fundamental, application, and technological studies. The annual volume of publications amounts to some 250 papers submitted from 100 leading national scientific institutions.
