Abstract

Bulk glass state Zr_52.5Ni_14.6Al₁₀Cu_17.9Ti₅ alloy sample with a diameter of 6 mm was prepared by melt injection. Its thermal properties were determined by DTA and DSC analyses. The critical cooling rate for glass formation in Zr_52.5Ni_14.6Al₁₀Cu_17.9Ti₅ alloy was evaluated to be 13.4 K/s, 19.0 K/s and 32.6 K/s from the empirical model and the kinetic model of glass formability respectively by using the DTA and DSC data. The real cooling rate in center of wedge-shaped samples was estimated by testing the glass state area on the longitudinal cross sectional structure of the wedge-shaped samples. The key factors which affect crystallization and growth were discussed.
