Computational-Experimental Processing of Boride/Carbide Composites by Reactive Infusion of Hf Alloy Melts into B4C

Abstract

This project primarily investigated computationally the infusion of liquid elements from the Hf family (i.e., Hf, Ti and Zr) into a capillary to understand the effects of surface tension and viscosity during processing of melts with a packed bed of B4C to form boridecarbide precipitates. Although the ultimate goal of the research endeavor is to enhance significantly the oxidation resistance of ultrahigh temperature ceramic composites (UHTCC), the processing of these reactive metals and non-metals must be improved dramatically to control the eventual development of the oxide scale.
