摘要
根据合金凝固过程中的守恒定律和传输原理 ,建立了纤维增强二元铝合金的凝固模型。利用所建立的模型 ,对Al2 O3 /Al Cu合金复合材料凝固时溶质传输和分布进行了数值模拟 ,研究了复合材料凝固时溶质偏析对纤维 /基体界面的影响。模拟结果与实验结果吻合较好。
The solidification model of fiber reinforced binary aluminum alloy was established according to the conservation law and the transfer principle of alloy solidification. The numerical simulation of the solute transfer and the solute distribution was carried out on Al 2O 3/Al Cu composite by the established model. The effect of solute segregation during soldification of the composite on the fiber/matrix interface was studied. The calculated values coincide with the experimental results on the whole.
