摘要

The microstructure and martensitic phase transformation behavior of the Ni_(50)Mn_(36)In_(14) melt-spun ribbons were investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) and differential scanning calorimetry (DSC). The results show that fine crystal grains with preferential orientation have been obtained in the rapidly quenched ribbons, the martensitic transformation temperatures of the as-cast ribbon are low, and increased after heat treatments. The reason is clarified as the variation in degree of order and internal stress.
