ABSTRACT CuAl10Ni5Fe4 alloy powders were successfully produced using the planar flow casting method, known as the continuous ribbon production process. Cooling the textured wheel to -5 ºC resulted in a much finer microstructure in comparison to uncooled wheel powders. The microstructure of the powders, in case of the cooled wheel, consisted of β′ martensite, which resides inside the colonies, and proeutectoid α phase at colony boundaries. The martensite start and finish temperatures for uncooled wheel powders were obtained as 221 ºC, and 174 ºC, respectively. The Ms and Mf temperatures for cooled wheel powders were measured as 207 ºC, and 135 ºC, respectively. It is observed that the magnetic properties of the produced powders change with the amount of β′ martensite.

平面流铸法生产的镍铝青铜粉末的表征

摘要 CuAl10Ni5Fe4 合金粉末使用平面流铸方法成功生产，称为连续带生产工艺。与未冷却的车轮粉末相比，将带纹理的车轮冷却至 -5 ºC 会产生更精细的微观结构。在冷却轮的情况下，粉末的微观结构由位于集落内部的 β' 马氏体和集落边界处的先共析 α 相组成。未冷却车轮粉末的马氏体起始温度和结束温度分别为 221 ºC 和 174 ºC。冷却后的车轮粉末的 Ms 和 Mf 温度分别测量为 207 ºC 和 135 ºC。观察到生产的粉末的磁性能随着β'马氏体的量而变化。
