Abstract
The invention includes a method for producing high-density composites of metallic glass alloy powders in combination with a refractory metal powder, and includes related methods for producing metallic glass alloys. The invention, in one aspect, employs a system of monitoring the temperature and hot isostatic pressing conditions during the consolidation of metallic compositions in order to produce higher densities and materials of a larger diameter, for example. In another aspect, the invention involves method whereby a third interfacial phase at a metallic glass alloy/refractory metal interface is effectively controlled to produce composites with advantageous properties.
