Title: | Multi-layer laminated Pd-based metallic glass with enhanced plasticity | Authors: | Ma, J Chan, KC Xia, L Chen, SH Wu, FF Li, WH Wang, WH |
Issue Date: | 10-Dec-2013 | Source: | Materials science and engineering. A, Structural materials : properties, microstructure and processing, 10 Dec. 2013, v. 587, p. 240-243 | 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. | Keywords: | Blocking effect Metallic glass Plasticity Structure relaxation Thermoplastic bonding |
