Evolution of mechanical characteristics of metallic glass Co-Fe-Cr-Si at annealing

摘要

Evolution of mechanical properties and structure of metallic glass is investigated. Stress - strain diagrams at different annealing temperatures are found. Changing of microhardness and plasticity in a wide temperature range is determined. Correlation between Young's modulus and microhardness is established. Evolution of surface layers in conditions of annealing and regularities of crystallization of surface and bulk of metallic glass are researched.
