包含 Ti3Ni4 共格沉淀物的 Ti-51Ni (at%) 合金表现出热诱导 B2-R 转变。如果 Ti3Ni4 在拉伸应力下形成,它会优先取向,使其习惯平面垂直于拉伸轴。据报道,在此类样本中,会发生应力诱导的反向 R-B2 转变。在本研究中,通过红外相机和原位X射线分析研究了应力引起的反向R-B2转变行为。红外相机观察表明,在相机分辨率范围内,通过施加拉应力,样品的温度均匀降低。原位 X 射线分析表明,应力诱导的反向 R-B2 转变和 R 相变体的重排在样品中同时发生。
Ti-51Ni (at%) alloys including coherent precipitates of Ti3Ni4exhibits thermally-induced B2-R transformation. If the Ti3Ni4is formed under tensile stress, it orientates preferentially so that its habit plane becomes perpendicular to the tensile axis. In such specimens, stress-induced reverse R-B2 transformation is reported to occur. In the present study, the stress-induced reverse R-B2 transformation behavior was studied by infrared camera andin situX-ray analysis. The infrared camera observation revealed that the temperature of the specimen decreases homogeneously by the application of tensile stress within the resolution of the camera. Thein situX-ray analysis revealed that stress-induced reverse R-B2 transformation and rearrangement of variants of the R-phase occurs simultaneously in the specimen.
