Abstract

Internally oxidized iron alloys and alpha -Fe were deformed at 650 similar 850 degree C, and some activation parameters were obtained. Stress exponents, apparent activation energies and activation volumes were similar to those of alpha -Fe. High temperature deformation of these alloys is controlled by lattice diffusion. The average internal stresses in these alloys were slightly higher than in alpha -Fe. The effective stress exponent of the average dislocation velocity was 2 similar 3 and had slight temperature dependence.
