    Abstract:

    The research progress on the refrigeration performance of Ni-Mn-Ti based all-d-metal Heusler alloy was reviewed. The crystal structure and atomic occupancy of this alloy series were introduced. The crystal structure is L21 or B2 ordered structure, in which Ti atom with the least valence electrons takes the place of the original mainSgroupSelements. The treatment technology and doped elements have a certain effect on the martensitic transformation temperature and Curie temperature. The martensitic transformation temperature can be adjusted to near the room temperature by these means to achieve the purpose of practical application. The refrigeration methods and principles of Ti-Mn-Ti based all-d-metal Heusler alloy were emphatically analyzed, and the development of the refrigeration properties of Ti-Mn-Ti based Heusler alloy in the future was prospected.
