Modulated Structures, Nanocrystals and Quasicrystals in Mg-Zn-Y Alloys

  • Anandh Subramaniam (a1) and S. Ranganathan (a2)

Abstract

The formation of the icosahedral phase, BCC (Body centred cubic) phase and nanocrystals are seen in the as-cast alloy with nominal composition of Mg4Zn94Y2. FCC (face centred cubic) phase and modulated structures are formed in the alloys with higher Y content (10% and 25% Y respectively). These phases are analysed keeping in view their relation to the quasicrystals of the Mg-Zn-Y system.
