Effect of Aging on Martensitic Transformation in a Shape Memory Ti-40.5Ni-10Cu Alloy
Department of Materials Science and Engineering, Faculty of Engineering, Osaka University,
Effect of aging at 873K on the two-step transformation of a Ti-40.5Ni-10.0Cu alloy, which contain Ti slightly lower than 50at%, was studied. It was found that the start temperature of the B2-B19 transformation and that of the B19-B19' transformation increase with increasing aging time. The start temperatures of the reverse transformations also increase. The temperature range of the two-step transformation decrease with increasing aging time. The change of transformation behavior is caused by phase decomposition of B2 phase through aging. The aged Ti-40.5Ni-10.0Cu alloy is composed of the B2 phase and the C11b phase
