Effect of strain hardening and volume fraction of crystalline phase on strength and ductility of bulk metallic glass composites

Continuum finite element analyses are performed to ascertain the role played by the volume fraction (V-f) and strain hardening behavior of crystalline reinforcements on the strength and ductility of bulk metallic glass matrix composites (BMGCs). Results show that a highly strain hardening elongated dendrite with V-f similar to 45% would make the BMGC ductile without any penalty on the strength. These results provide design guidelines for strong yet ductile BMGCs. (C) 2016 Elsevier Ltd. All rights reserved.
