摘要
用激冷甩带法制备了Ti-46Ni合金薄带,用扫描电子显微镜、X射线衍射仪、示差扫描热分析仪和弯曲试验研究了合金薄带的组织特征、相变行为和形状记忆效应。结果表明,铸态及400~600℃退火态Ti-46Ni合金薄带的显微组织形态呈树枝状,晶粒细小,由B19?马氏体和B2母相组成;在冷却、加热过程中,该合金薄带发生一阶段马氏体相变;铸态和退火态Ti-46Ni合金薄带均具有良好的形状记忆效应。
Ti-46Ni alloy ribbons were fabricated by melt-spinning. The microstructure characteristics,the transformation behaviors and shape memory effect of the Ti-46Ni alloy ribbons were investigated by SEM,XRD,differential scanning calorimetry and bending test. The results show that the microstructure morphologies of as-cast and 400~600 °C annealed Ti-46Ni alloy ribbons are dendritic,the grain is small,and the composition phases are martensite（B19？） and parent phase（B2）. The one stage martensite transformation appears upon cooling and heating. The as-cast and annealed Ti-46Ni alloy ribbons are both of excellent shape memory effect.
