Conclusions 1. Single-crystal molybdenum can be used, in addition to refractory niobium-, tantalum-, molybdenum-, and tungsten-base alloys, as a structural material for components that operate at very high temperatures; under these conditions single-crystal molybdenum has a strength comparable with that of the refractory alloys combined with a reserve of ductility greater than these alloys possess. 2. The maximum plastic deformation realized in single-crystal molybdenum during thermocyclic creep at high temperatures is considerably greater than that obtained in short-term tests. 3. The failure of single-crystal molybdenum under alternating nonisothermal stressing is determined by the rate at which the time processes occur, and it takes place as a result of cyclic creep after the maximum ductility has been reached and is quasistatic in character.
