摘要:

金屬基復合材料可以通過基體合金成分改變、增強體的形態和種類選擇及工藝控制等要素獲得不同的材料特性，因而具有很強的可設計性。在金屬基復合材料性能設計中，界面狀態的控制是核心內容。歸納了作者近幾年在金屬基復合材料界面控制研究方面的研究工作，包括利用工藝技術方法控制C f/Al有害界面反應，獲得TiB 2/Al自潤滑界面；利用基體合金化方法控制SiC/Al和C f/Al有害界面反應，獲得W/Cu固溶體界面等方面的理論與實踐。研究表明，采用材料制備工藝和基體合金化等方法控制界面反應熱力學和動力學過程可以實現抑制有害界面產生及獲得有益界面，而且是十分簡捷、有效和低成本的方法。

Abstract:

The properties of metal matrix composites (MMCs) can be tailored by changing the matrix compositions, the shape and type of reinforcements. Among the design of MMCs, the control of interfacial conditions is the key point. In this paper, the research progress on the control of MMCs interfaces has been reviewed, including the inhibition of harmful interfacial reaction in C�璮/Al composite and generation of self lubricating interface in TiB2/Al composite by process control; the control of harmful interfacial reactions in SiC/Al and C�璮/Al composites by matrix alloying; the obtaining of W/Cu solid solution interface. It has been proven that the process control and matrix alloying are simple, effective and low�瞔ost methods to avoid harmful interfaces and acquire beneficial interfaces by suppressing the thermodynamics process.��
