摘要：
Texture of Ti52Ni38Cu10 rapidly solidified ribbons was investigated. Characterization of some of the properties such as transformation temperatures, deformation behavior, transformation strain, microstructure etc. was also carried out for the rapidly solidified ribbons in as-spun condition and after heat-treatment at 1073 K. The transformation temperatures of the ribbon specimens are found to be less than those of ingot specimens. As-spun ribbons were found to be slightly amorphous in nature, while after heat-treatment they became completely crystalline. Asspun and heat-treated ribbons show strong (200) fiber texture. From the thermomechanical studies it was observed that the hysteresis of the heat-treated ribbon specimen decreased whereas the transformation strain and the transformation temperatures showed an increase with increase in stress.
