| 摘 要： | 为了揭示时效和球磨后Nb掺杂Ni-Mn-Ga合金的相变演化,采用SEM、EDS、XRD、DSC和交流磁化率测试等技术研究时效和球磨双相Nb掺杂Ni-Mn-Ga合金的显微组织和相变。铸态合金主要由层状第二相组成,随着第二相含量增加,合金的马氏体相变逐渐减弱。1173 K淬火后第二相从层状转变为致密的棒状,且合金的马氏体相变增强。经673和873K时效后,含有较少第二相的3%Nb合金表现为一步相变,而含有较多第二相的6%Nb和9%Nb合金表现为两步马氏体相变和居里转变。球磨双相颗粒的马氏体相变和居里转变消失,1073 K退火后基体的高有序结构得到恢复,从而导致双相颗粒的马氏体相变和居里转变恢复。
