| Abstract | The effect of deformation on the stress-induced martensitic transformation behavior of the Ti44Ni47Nb9 alloy was studied by DSC and cryogenic tensile tests at M-s+30 degreesC. DSC measurements show that the process of stress-induced martensitic transformation is completed as the tensile strain reaches to about 14%, and the transformation is inhomogeneous microscopically. The reverse transformation temperature interval of the stress-induced martensite was found to be much smaller than that of the thermally induced martensite. The experimental results also indicate that A's temperature of the first reverse transformation, its temperature interval and transformation heat are all increased with increasing the level of deformation. However, the wide hysteresis effect due to the deformation vanished after the first heating. The transformation heat in the subsequent transformation cycle, the forward transformation start temperature of the first cooling and the reverse transformation start temperature of the second heating are all decreased slightly with increasing deformation. |
