The true elastic limit of high-purity molybdenum, tungsten, and iron is shown to be of the order of 10−5 μ, where μ is the shear modulus. At higher stresses, linear reversible deformation occurs up to total strains of the order 10−3. The strain-rate sensitivity of the flow stress in this region is investigated and a possible rate controlling dislocation mechanism is discussed.

Face Centered

Recent studies have shown the presence of voids in several face-centered cubic metals after neutron irradiation at elevated temperatures. These voids were found when the irradiation temperature was above 0.3 Tm where Tm is the absolute melting point, and were ascribed to the agglomeration of lattice vacancies resulting from fast neutron generated displacement cascades. The present paper reports the existence of similar voids in the body-centered cubic metals tungsten and molybdenum.
