Bulk metallic glasses (BMGs) possess a unique set of mechanical properties that make them attractive structural materials. However, when loaded without constraint, BMGs fracture catastrophically due to formation of macroscopic shear bands and this behavior reduces their reliability. To address this
Lightweight and plastic Ti-based bulk-metallic-glass-matrix composites (BMGMCs) were fabricated by the Bridgman solidification. The β€-Ti dendrites were uniformly distributed within the glass matrix. By tailoring the withdrawal velocity, v, the linear dependences of the spanning length, s, and the vo
