Abstract

The microstructural investigation of a suction-cast Al₉₃Fe₃Cr₂Ti₂ bulk alloy reveals that an icosahedral phase forms together with monoclinic Al₁₃(Fe,Cr)₄ and tetragonal Al₃Ti in an α-Al matrix. The icosahedral phase is often surrounded by Al₃Ti particles indicating that the formation of the icosahedral phase strongly competes with the Al₃Ti phase. Chemical analysis reveals that Ti has a strong influence to stabilize the Al₃Ti phase. In contrast, both Cr and Fe are effective to stabilize the icosahedral phase.
