摘要: Abstract In the current work, tensile creep behaviors of a (Cu0.5Zr0.5)92Ta8 metallic glass composite were investigated. The precipitates and matrix in as-spun ribbons have nearly same compositions. addition Ta element enhances thermal stability binary Cu50Zr50 glass. apparent activation energies increase with applied stress, values strain rate sensitivity decrease from 0.39 to 0.16 increasing temperatures. correlationship energy volume suggests that largest corresponds smallest volume, vice versa. are noticeably smaller than reported values, which is related softening
