Abstract: We have demonstrated, for the first time, the enhanced plasticity of multi-layer Pd-based bulk metallic glasses (BMGs) synthesized by thermoplastic bonding (TB). The structural relaxation was minimized by using a low bonding temperature and a very short holding time. As compared to the as-cast and the two-layer BMG samples, the three-layer samples achieve larger plasticity. The fracture morphology of the multi-layer samples exhibit radiating-ridge patterns as compared to the river-like cell patterns observed in as-cast BMGs. The enhanced plasticity is due to the blocking effect of the bonding interface for the propagation of shear bands. Our research opens a promising way to synthesize BMGs with larger size and enhanced plasticity for potential structural applications.
