Fundamental Thermal and Mechanical Properties of Boride Ceramics

Abstract

The goal of the project was to investigate the fundamental factors that control the elevated temperature mechanical and thermal properties of ultra-high temperature diboride ceramics that are relevant to future Air Force needs related to hypersonic aviation and scramjet propulsion. The three main areas of research were: 1) structure-property relationships; 2) thermal properties; and 3) elevated temperature mechanical behavior of zirconium diboride and zirconium diboride-silicon carbide ceramics. Significant progress was made in each of the project areas.
