摘要

The crystallization behavior of Au₅₀Cu_25.5Ag_7.5Si₁₇ metallic glass after isothermal treatment at different temperatures throughout the entire supercooled liquid region is investigated by ultra-fast calorimetry. The isothermal crystallization products of the glass, especially in the relatively high temperature region, where was difficult to reach via conventional techniques, are identified. Based on the microscopic analysis of the crystallization products, the crystallization mechanisms of the glass at different temperatures are clarified. The grain size evolution of the crystalline phases upon isothermal treatment are discussed through the comparison of the theoretical calculation and experimental results.
