Abstract
This study examines the Martensite transformation of Ni-Ti Shape Memory Alloy. Fast, transformation temperature of Ni-Ti Shape Memory Alloy is measured by using Differential Scanning Calorimetry and Dynamic Mechanical Analysis. Since the result by DMA coinsides with that by DSC Measurement, the heat treatment temperature which influences with Martensite transformation temperature is investigated by DMA. Next, crystal structure is investigated by X-ray diffraction mater. Usually it is considered that the crystal structure of Martensite state is as B19 structure, While, the B2 is found in that state.
