A dislocation climb creep model is considered which does not require the production of immobile dislocations. The creep equation that results from the analysis iscreep rate=A&sgr;3sinh(B&sgr;1.5/kT)exp(−Q/kT),whereAandBare constants, &sgr; is the stress,Qis the activation energy of creep andkThas its usual meaning. This equation is quite similar to one previously proposed.
