摘要：
In this work, the dependence of microstructure of Fe-Al-Si alloy on conditions of reactive sintering was studied. It was shown that heating rate strongly affects the structure of this alloy. The microstructure consisting of uniformly distributed Al(2)Fe(3)Si(3) particles in Al(2)FeSi matrix can only be obtained in this material by rapid heating (over 300 K mm(-1)). Sufficient reactive sintering temperature to obtain Al(2)Fe(3)Si(3)-Al(2)FeSi two-phase structure is 750 degrees C. Further increase of the reaction temperature reduces porosity but causes a growth of Al(2)Fe(3)Si(3) particles. Reactive sintering process is completed during less than 10 min in the investigated material. Temperatures over 1050 degrees C produce material composed of FeSi, FeAl and Al(2)Fe(3)Si(3) phases. However, strongly exothermal reaction of FeSi formation causes melting of the sample. (C) 2009 Elsevier B.V. All rights reserved.
