摘要：

Transformation behavior of TiNiCr shape memory alloys with different aging treatment was investigated by DSC, scanning electron microscopy (SEM) and the D/max2500PC automatic X-ray diffraction equipment (XRD). The results indicate that with increasing of the aging temperature, the transformation temperature A(s) and A(r) increase but they decrease after 700 degrees C and TiNiCr alloy exhibits B2 -> R -> B19' two-stage martensitic transformation during cooling. Lots of Ti3Ni4 precipitants from aging treatment induce R phase transformation.
