Abstract
The microstructure of Mg 60+ x Cd 25− x Yb 15, x=0, 5, 10, Mg 50Cd 30Yb 20 and Mg 25Cd 65Yb 10 as-cast alloys has been examined by transmission electron microscopy. While the Mg 60Cd 25Yb 15 alloy showed only an icosahedral quasicrystalline phase, the magnesium rich alloys also showed a Zn 2Mg type (Mg,Cd) 2Yb Laves phase. The alloys showed nanosized particles of icosahedral phase. Eutectic microstructures involving the icosahedral phase were observed. A lamellar (50 nm) structure of icosahedral phase and Mg was observed, exhibiting a definite orientation relationship with the hexagonal axis along one of the twofold axes of the icosahedral phase. In the Cd-rich alloys the cubic Cd 6Yb approximant phase occurred, along with the icosahedral phase and intermediate structures in nanocrystalline form.
