Abstract
The tensile plastic deformation behaviour of a Ti-based metallic glass composite (MGC) lamella confined by commercially pure titanium (CPT) is investigated. It is found that a uniform plastic deformation is achieved in the CPT-confined MGC lamella, where the strain localization and necking is effectively suppressed. The MGC lamella sustains a true tensile strain exceeding 10% before fracture. A deformation mechanism of the amorphous/crystalline interface is proposed to interpret the plastic deformation of the MGC/CPT structure. The revealed significant intrinsic plasticity of the MGC suggests its potential application as an excellent coating for bulk ductile materials.
