Abstract

At high temperatures, the creep strain, ϵ, appears to be a function of a temperature (T), compensated time (t), namely te−ΔHRT, and the stress. X-ray analyses and plastic properties reveal that the same structures are developed at the same values of te−ΔHRT following creep at the same stress. Thus ϵ = ƒ(te−ΔHRT), for the same stress. When the creep rate, ϵ, is evaluated as a function of stress, σ, for the same structure ϵ = Se−ΔHRT φ(σ) where S depends on the structure and

Although B and n appear to be insensitive to structural changes attending creep of annealed alloys, they decrease with increasing solute additions and cold working. Transients attending loading and unloading and the coincidence of the activation energy for creep, ΔH, with that for self-diffusion suggest that high temperature creep might be ascribed to a dislocation climb process.
