摘要	Analysis electron microtechnique (AEM) and high resolution electron microtechnique (HREM) studies were conducted on a spray deposition Al-8.5Fe-1.3V-1.7Si(mass fraction, %) alloy to determine the characteristics of the intermetallic phases. The results show that the striking characteristics of the microstructures in as-deposited and as-extruded alloys indicate the presence of a large amounts of homogeneously distributed fine particles and a few coarse particles, while small amount of eutectics consisted of alpha (Al) and alpha -AlFeSi are found in local zone in as-deposited alloy. The fine particle is identified to be bce alpha -AlFeSi phase, and the coarse particles are monoclinic alpha -Al(13)Fe(4) equilibrium phase, bce alpha -AlFeSi phase and newly found hexagonal h-AlFeSi metastable phase. In alpha -Al(13)Fe(4), stacking faults on (100) and (001) plane and microtwin on (100) twinning plane are frequently observed. The extra reflection spots in alpha -AlFeSi reflection pattern can be induced by alpha -AlFeSi superstructure. The hexagonal metastable phase transforms to bcc phase, and the compositions of two phases are very similar. A close crystallographic orientation relationship between hexagonal and bcc phases are determined, and HREM image shows that the interface between them is coherent.
