Abstract Relaxation behaviors of highly rejuvenated Zr50Cu40Al10 bulk metallic glass was investigated using synchrotron X-ray scattering coupled with differential scanning calorimetry. The relaxation of rejuvenated volume is found to correspond to a marked exothermic event prior to the glass transition. High-energy synchrotron X-ray measurements of the structure factor show that annihilation of rejuvenated volume correspond to a sharpening of the scattering peaks. The calculated reduced pair distribution function suggests that the atomic re-arrangement in the second shell are largely responsible for the reduction in the free volume and decrease in full-width at half-maximum of the Total Structure Factor observed during structural relaxation. Mechanical properties in the highly rejuvenated metallic glass were evaluated as a function of annealing temperature.

通过原位同步加速器 X 射线散射研究高度再生的块状金属玻璃的弛豫行为

摘要 使用同步加速器 X 射线散射结合差示扫描量热法研究了高度再生的 Zr50Cu40Al10 块状金属玻璃的弛豫行为。发现再生体积的松弛对应于玻璃化转变之前的显着放热事件。结构因子的高能同步加速器 X 射线测量表明，再生体积的湮灭对应于散射峰的锐化。计算的减少对分布函数表明，第二壳中的原子重新排列主要是造成自由体积减少和结构松弛期间观察到的总结构因子的半高处全宽减少的主要原因。
