Stresses ranged from 250 to 20,000 psi, temperatures from 23 to 600°C, and strain rates from I0~5 to 10"' sec"'. Effects on mechanical properties of stress, temperature, and mechanical and thermal histories were studied. Strength properties obtained from compression, tension, shearing, and torsion tests were analyzed and compared, and the results are in close agreement. The fiow stress increased with increasing strain rate and decreased with increasing temperature, indicating that one or more thermally activated deformation mechanisms control plastic deformation in this domain of testing. Work performed under the auspices of the U. S. Atomic Energy Commission.
