摘要
综述了Al-Fe-Si系铝角相图及相研究方面的工作,给出了富铝端Al-Fe-Si三元系中最可能存在的液相、固相区及某些特定条件下的截面图,提供了工业纯铝中可能存在的物相的晶体学数据及部分热力学数据,简要介绍了相的一船形成条件和转变规律,着重分析讨论了各种品型的α相和β相的晶体结构和形成条件。文章还对目前研究工作中存在的问题进行了简要分析。
The composition of commercial-purity aluminium, the types and distribution of intermetallic com-pounds have been found to have very important effects on the properties of the semi-products and finalproducts. The aluminium -side corner phase diagram in aluminium-iron -silicon system and related researchwork have been systematically reviewed. Crystal structure and thermo-dynamic parameters of the com-pounds in the commercial-purity aiuminium are introduced. Formation and transformation of the com-pounds are analyzed, with more attention to the crystal structure and formation conditions of α and β phaseswith different structures. Existing problems in present study on the compounds in the commercial-purity al-uminium are also discussed.
