Abstract

A new Co43Fe20Ta5.5B31.5 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.
