Abstract

Microstructural evolution including the stability of icosahedral phase (I-phase) in Mg_95.9Zn_3.5Gd_0.6 alloy, before and after extrusion, has been investigated. The results indicate that the I-phase in Mg_95.9Zn_3.5Gd_0.6 alloy is a face-centered icosahedral quasicrystal with stoichiometric composition of Mg₄₂Zn₅₀Gd₈ and that this I-phase has excellent thermal stability up to 713 K. The W-phase and W′-phase, which are considered approximate crystalline equivalents of I-phase, have also been observed in the as-extruded alloy. © 2006 Acta Materialia Inc.
