Abstract:
1. A method of forming a bulk metallic glass composite material comprising: providing a bulk metallic glass comprising a plurality of dendrites dispersed within a glassy matrix, said bulk metallic glass being provided at a temperature below the glass transition temperature of the bulk metallic glass; heating the bulk metallic glass to a composite formation temperature above the solidus temperature and below the liquidus temperature of the bulk metallic glass such that the glassy phase of the bulk metallic melts to form a bulk metallic glass solution comprising the plurality of dendrites homogenously distributed within the liquid glassy phase; holding the bulk metallic glass at the composite formation temperature until the microstructural length of the plurality of dendrites increases until said microstructural length is on the order of the theoretical length scale (R quenching the bulk metallic glass to below the glass transition temperature of the bulk metallic glass to form a bulk metallic glass composite material comprising the plurality of dendrites homogenously disposed within the glassy matrix.
