摘要: High-temperature deformation of a ZrTiCuNiBe bulk metallic glass (BMG) is investigated by compression tests in the supercooled liquid region. When temperature decreased or strain rate increased, amorphous alloy exhibits usual Newtonian/non-Newtonian transition behaviour. Using specific heat treatments, partially crystallized alloys are produced, associated microstructures characterized and volume fractions crystal measured. The interaction between high-temperature crystallization appropriate mechanical testing. According to these measurements, partial responsible for significant increase flow stress promotion non-Newtonian Deformation does not significantly change fraction, composition size crystal. flow-stress with analyzed under different hypotheses. We conclude that cannot be interpreted through compositional chang...
