Abstract

The apparent activation volume measured during high-temperature deformation of molybdenum spheroidized steel was found to be independent of temperature, stress and strain. The values obtained for the activation volume agree reasonably well with a model based on the non-conservative motion of jogs on moving screw dislocations. The steady-state creep of this alloy is discussed in terms of currently available diffusion-controlled dislocation mechanisms. © 1974.
