icosahedral quasicrystalline and Mg4Zn7 particles are also observed. The T phase is confirmed having a body-centered orthorhombic structure that is transformed from the body-centered tetragonal structure Mg12Ce phase due to the partial substitution of Mg atoms by Zn. Key words: Mg-6Zn-1Y-1Ce alloy; rapid solidification; T phase; icosahedral quasicrystalline; Mg4Zn7 phase; W phase 1 Introduction Mg alloys......
