A New Nd--Based Bulk Metallic Glass
|
Abstract:
A new Nd61Fe30Zn9 bulk metallic glass with a diameter of 2.5 mm was obtained using copper mold casting. No glass transition temperature or supercooled liquid region was observed by using conventional DSC-7 facility. The crystallization temperature for the bulk sample is 730 K, which is about 70 K lower than that of Nd60Fe30Al10 bulk metallic glass. The melting characteristics of Nd61Fe30Zn9 alloy show that its compositional is at a eutectic point, but the alloys exhibit non-eutectic microstructure due to high tendency of undercooled ability.
