The tensile properties of annealed tantalum, like those of other body-centered-cubic metals, were found to depend markedly on test temperature. The yield strength increased sharply from about 39 Ooo psi at room temperature to over 125 000 psi at -195'C. However, a transition from a ductile to a bri

The activation energy, H, the activation volume, w\*, and the frequency factor, Y, for the plastic deformation of niobium at low temperatures (T < 0.2 T,) were derived from creep tests. The values of H and e\* for r\* = 1 kg/mm2 were 0.75 eV and 47bS respectively, decreasing with increase in stress.
