通过两因素三水平的正交设计实验和极端顶点的混料设计实验,研究了不同含量的Ti,B,RE对细晶铝锭的联合细化效果;并根据正交设计实验的方差分析和混料设计实验非线性方程的最小二乘法求解,寻求Ti,B,RE联合细化的最优工艺.结果表明:正交设计和混料设计得到的最优工艺基本一致,即Ti=0.01%,B=0.001%,RE=0.1%,Ti/B=10/1,Ti/RE=1/10,且Ti/B对细化效果影响显著,而Ti/RE的影响次之.为了验证最优组合的细化效果,将0.01%Ti+0.1%RE+0.001%B的细晶铝锭、0.01%Ti的细晶铝锭、0.01%Ti+0.3%RE的细晶铝锭和0.01%Ti的Al-5Ti-IB分别细化6063铝合金,发现0.01%Ti+0.1%RE+0.001%B的细晶铝锭的细化效果最好.
