OSTI ID:6244500
Molybdenum-rhenium alloys containing less than 15% Re have been investigated for space-nuclear power-system applications. A ductile-brittle transition temperature of less than 135/sup 0/K has been demonstrated for recrystallized Mo-13 wt % Re alloy. Thermophysical properties have been measured over the temperature range from ambient to 1500/sup 0/K and the elastic modulus determined to be 289 GPa. Thermal conductivity of the alloy at temperature has been demonstrated as comparable to pure molybdenum. Fabricability of the material has been demonstrated and an investigation of weld characteristics initiated. Optimization of alloy composition for the planned application is continuing.
