Abstract
Rhenium was added to MoSi2 in two concentrations and billets were made by hot pressing powders. The microstructures obtained are reviewed. Fracture toughness was measured at 20 and 800°C, hardness was measured at 20°C, and oxidation resistance was determined at 500°C. Toughness was not enhanced, but hardness and oxidation resistance were. However, the base alloy made for comparison had better properties than those given in published reports.
