对Cu-10%Co-10%Fe (质量分数)亚稳液态组元不混溶合金开展了气体雾化快速凝固实验, 制备了富Fe-Co相球形粒子均匀分布于基体Cu的复合粉末, 建立了Cu-Co-Fe合金雾化液滴冷却过程中的温度场、浓度场和液-液相变动力学控制方程, 研发了耦合合金热力学和相变动力学的模拟方法, 模拟分析了Cu-10%Co-10%Fe合金雾化液滴的凝固组织形成过程. 实验和模拟结果表明, 在气体雾化快速凝固条件下, 液-液相变过程中富Fe-Co相液滴Marangoni迁移和Ostwald熟化的影响很弱, 粉末中心绝大部分区域内富Fe-Co相粒子的空间分布均匀. 对于直径小于220 mm的Cu-10%Co-10%Fe合金粉末, 富Fe-Co相粒子的平均半径Ra和数量密度N与雾化粉末直径d之间符合指数关系.
