For in-situ Ti₄₈Zr₂₀Nb₁₂Cu₅Be₁₅ metallic glass matrix composites (MGMCs) upon cold rolling, the yield strength is obviously enhanced, and the plasticity instability is effectively alleviated. The increase in yield strength in such kinds of composites is due to the fact that the work hardening of dendrites overwhelms the softening of the amorphous matrix. A quantitative model of predicting yield strengths with rolling straining in MGMCs is successfully established. This provides useful guidances for structural applications of ductile MGMCs.

钛基金属玻璃复合材料冷轧后的硬化压倒性软化

对于冷轧原位Ti ₄₈ Zr ₂₀ Nb ₁₂ Cu ₅ Be ₁₅金属玻璃基复合材料（MGMCs），屈服强度有明显提高，塑性不稳定性得到有效缓解。这种复合材料的屈服强度提高是由于树枝状晶体的加工硬化压倒了无定形基体的软化这一事实。成功建立了MGMC中滚动应变预测屈服强度的定量模型。这为延性MGMC的结构应用提供了有用的指导。
