Abstract

In-situ β phase/Zr_56.2Ti_13.8 Mb_5.0Cu_5.6Ni_5.6Be_12.5 BMG (bulk metallic glass composites)composites were prepared by low pressure casting combining with water-cooling copper mould and by the melt water-quenching method, respectively. The microstructure and ambient compressive properties of the composites were investigated. It is revealed that the microstructure characteristics of the composites, including the volume fraction, morphology and size of β phase, sensitively depends on the processing conditions. Lower cooling rate can result in the formation of more and coarser β phase, in which different preparation methods, sample shapes and size can lead to different cooling rate. Ambient compressive properties of the composites are controlled by microstructural characteristics, where more and coarser β phase can significantly improve the macro-plasticity of the composites.
