Polycrystalline alloy Ni 52Mn 24.4Ga 23. 6 was prepared by repeated vacum induction melting, and bonded Ni 52Mn 24.4Ga 23.6 magnets were prepared by powder compression method. The e ffects of different moulding and annealing processes on the microstructure and p roperties of Ni 52Mn 24.4Ga 23.6 alloy were investigated by dif ferential scanning calorimetry(DSC) analysis, optical microscopy and scanning mi croscope. The results show that coarse grains can be obtained at low cooling rat e. The fixed martensite transformation temperature of the alloy is obtained and the nucleation and growth of martensite of Ni 52Mn 24.4Ga 23.6 alloy is promoted by two-step annealing process.

采用真空感应熔炼法制备了多晶Ni52 Mn2 4 4 Ga2 3 6 合金 ,用粉末压缩压制的方法制作粘结Ni52Mn2 4 4 Ga2 3 6 磁体 ;通过显微组织观察和差热分析 (DSC)的方法研究了不同的浇铸方式和退火工艺对多晶Ni52 Mn2 4 4 Ga2 3 6 合金铸锭组织和性能的影响。结果表明 ,缓慢冷却的合金液能得到晶粒粗大的合金铸锭 ;两步退火工艺能使合金铸锭具有确定的马氏体转变点 ,并促进马氏体变体的形核和长大。
