摘要：
Al-steel clad material has been widely used due to its excellent performance both with good mechanical property of steel and corrosion resistance, high thermal conductivity, low density of Al. The metallurgical bonding between the Al and the steel will be damaged when the intermetallic compound generated in the interface. It seriously deteriorates the performance of the material. So it's important to inhibit the growth of the intermetallic compound for develop the Al-steel clad material. This paper summarizes the formation and inhibition mechanism of Fe-Al intermetallic compound. Introduce the type and crystal structure of the most common Fe-Al intermetallic compound phases. Discuss the mechanism and the subsequence on the formation of the intermetallic compound from the aspects of thermodynamics and dynamics.Then compare the effect of different alloy element on the formation of the Fe-Al intermetallic compound. Especially, the inhibition mechanism of Si on the formation of Fe-Al intermetallic compound is emphatically considered. © 2016, Materials Review Magazine. All right reserved.
