通过热轧和冷轧工艺制备了0.2mm厚的Co41Ni33Al26合金带材,采用1350℃×5h水冷对该带材进行了淬火热处理,用金相显微镜观察了其组织.用微分差热分析仪(DSC)测定了其马氏体转变温度,并用动态热机械谱仪(DMS)研究了其相变及阻尼能力.结果表明,0.2mm的Co41Ni33Al26合金带材的基体为竹节状的粗大再结晶晶粒,其马氏体相变温度比1.5mm厚的板材高约45℃;降温过程中合金带材在140～25℃温度范围出现阻尼峰,其阻尼峰宽明显大于马氏体相变温度范围,后者为121～78℃,表明有新的应力诱发马氏体相变出现;Co40Ni33Al27合金带材的阻尼能力超过0.04,并且温度范围宽,有望成为新型阻尼材料.
