通过求解时间相关的非稳态扩散方程,详细分析了共晶强制生长初始过渡过程并导出其非稳态溶质扩散场,发现生长速度V 是初始过渡区溶质分配的最主要影响因素,其次为共晶相间距λ、溶质扩散系数D 等系统参量,透明共晶系CBr_4-11.1wt-%C_2Cl_6实验证实了理论分析的规律。
Considering initial transition processing is important in studying pattern selec-tion because the non-linear dynamic conduct is dependent upon early stage and path in crystalgrowth processing.The initial transition processing has been analysed in detail a
