摘要：
The microstructure and its evolution of a Zr41Ti14Cu12.5Ni10Be22.5 bulk metallic glass (BMG) annealed under high pressure and below glass transition temperature are investigated by using high resolution transmission electron microscope, differential scanning calorimeter, x-ray diffraction, ultrasonic study, and density measurements. It is found that high pressure annealing below T-g results in a microstructural transformation from short-range order to medium-range order in the BMG; the BMG with medium-range order structure exhibits different structural, thermal and acoustic properties.
