摘 要: 根據(jù)合金凝固過程中的守恒定律和傳輸原理，建立了纖維增強(qiáng)二元鋁合金的凝固模型。利用所建立的模型，對(duì)Al2O3/Al-Cu合金復(fù)合材料凝固時(shí)溶質(zhì)傳輸和分布進(jìn)行了數(shù)值模擬，研究了復(fù)合材料凝固時(shí)溶質(zhì)偏析對(duì)纖維/基體界面的影響。模擬結(jié)果與實(shí)驗(yàn)結(jié)果吻合較好。

Abstract: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 Al2O3/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.
Key words: composite；aluminum alloy；solidification； segregation；numerical simulation
