合金添加剂对SiCp/Al复合材料的高温化学稳定性有重要影响。利用威尔逊方程和扩展的Miedea模型计算了多元体系的活度，并从热力学的角度研究了合金元素的添加对SiCp/Al复合材料高温化学反应的影响。计算结果表明，大部分合金元素如铜或硅的加入可抑制界面化学反应，而镁等合金元素的加入可促进界面化学反应。实验结果与计算结果吻合较好。(C)2004爱思唯尔B.V.保留所有权利。
Alloying additions have an important effect on the chemical stability of SiCp/Al composites at high temperature. Using the Wilson equation and an extended Miedema model, the activity in a multiple-component system was calculated and then the influence of alloying element additions on the chemical reaction of SiCp/Al composites at high temperature was investigated from a thermodynamic viewpoint. The calculation results showed that the addition of most alloying elements such as copper or silicon could reduce the interfacial chemical reaction but the addition of some alloying elements such as magnesium could promote the reaction. The experimental results were in agreement with the calculation results. (c) 2004 Elsevier B.V. All rights reserved.
