- Abstract
- A new class of bulk metallic glass composite is introduced that possesses a large tensile ductility along with significant work hardening capacity under tensile stress mode. It shows that the deformation of the composite is initiated in the harder amorphous matrix, followed by the plastic deformation of softer crystalline dendrites at a later deformation stage. This unique property is attributed to the deformation-induced transformation of crystalline dendrites to martensite phase. (C) 2011 Acta Materialia Inc. Published by Elsevier Ltd.
