Abstract

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 volume fraction, v_f, of dendrites can be determined as: s=-30v+139 and v_f=-12v+50, respectively. The plasticity of Ti-based BMGMCs was extensively studied in terms of the interdendrite spacing and the volume fraction of dendrites. An inverted U-shaped characteristic of the plasticity with the withdrawal velocity has been identified and explained. The present research gave a way for the design of plastic BMGMCs. © 2010 Elsevier B.V.
