摘　　要：总结了近年来国内外对Ni-Mn-Ti基全d族Heusler合金制冷性能的研究进展。介绍了该系列合金的晶体结构和原子占位,晶体结构为价电子数最少的Ti原子取代原主族元素的位置上形成L21或B2有序结构。改变处理工艺和掺杂元素对马氏体相变温度与居里温度有一定影响,可以借此手段将相变温度调节到室温附近以达到实际应用的目的。着重分析目前Ni-Mn-Ti基全d族Heusler合金的制冷手段及其原理,对未来该系列合金在制冷性能方面的发展进行了展望。The research progress on the refrigeration performance of Ni-Mn-Ti based all d-group 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 main group elements.The treatment technique 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 to achieve practical application.The refrigeration methods and principles of Ni-Mn-Ti based all d-group Heusler alloy were emphatically analyzed,and the development of the refrigeration properties of Ni-Mn-Ti based Heusler alloy in the future was prospected.
