Glass-Forming Ability and Thermal Stability of Gd_55-xNd_xCo₂₀Al₂₅ Metallic Glass

Abstract:

The effects of Nd substitution in Gd_55-xNd_xCo₂₀Al₂₅ (x=0, 5, 10, 15 and 20) amorphous ribbon samples on glass-forming ability and thermal stability are studied. The change of microstructure cannot be identified by X-ray diffraction. The forecast of glass-forming ability following Fang’s method shows the increase with x, which is further confirmed experimentally by the increasing reduced glass-transition temperatures. The thermal stability has a minimum at x=10, and it is suggested to be due to the different effects of the reducing of Gd and the increase of Nd.
