| 摘 要： | The transformation behavior of a TiNiCu shape memory alloy electrolyticaUy charged with hydrogen was investigated by means of different scanning calorimetry (DSC), optical microscope and X-ray diffraction (XRD). The results showed that inter- and inner-granular hydrides formed after charging with hydrogen, and the hydrides suppressed martensitic transformation. The electrolyticaUy charged hydrogen can be easily released by heat treatment and the transformation occurred again, which was verified by the DSC and XRD experiments.
