OSTI ID:4051394
Refractory metals were evaluated for potential use in high-temperature, turboelectric, space powerplants using potassium as the working fluid. In isothermal-capsule tests to 2000 deg F, corrosion of wrought niobium and niobium- 1% zirconium alloy was negligible except when the metals were combined with nickel alloys. In 50 hr ot Rankine-loop iesis to 1800 deg F, molybdenum resisted attack best of the refractory metals tested. Limited mechanical properties tests are described. Two niobium alloy loops are under construction, and the first vacuum chamber is complete. (auth)
