Abstract
Thermally induced intermartensitic transformation in polycrystalline Ni 52.5Mn 23.7Ga 23.8 has been investigated by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). It is found that after annealing at 500 °C for 4 h an intermartensitic transformation, seven-layered orthorhombic martensite (7M) → five-layered tetragonal martensite (5M), appears in polycrystalline Ni 52.5Mn 23.7Ga 23.8 alloy quenched from 800 °C, where the sequence of phase transformations is austenite phase (A) → 7M → 5M during cooling and 5M → 7M → A during heating. The intermartensitic transformation is an independent phase transformation, but the critical transition temperatures and the transformation temperature ranges of 7M → 5M are strongly affected by the martensitic transformation.
