摘要	A new Co43Fe2Ta5.5B31.5 metallic glass matrix composite was cast with in situ precipitated crystalline dendrite phases. This composite has particular plasticity properties with a large stress rise after yielding under uniaxial compressive test, which offsets the strength loss, together with local shear deformation and plastic flow within the vein-like structure. In addition, some shear bands - also with the vein-like structure - are observed ahead of the cracks. This indicates that the local shear deformation is triggered by the local shear softening mechanism. (C) 2008 Acta Materialia Inc. Published by Elsevier Ltd. All rights reserved.
