Abstract : The ffect of re on the cr ep rate of hipuriolycrystalline Al in the interme ia t p rature r ge wa inigyucting creep tests at a series of different stresses and by decreasing thug the course of primary and secondary creep. Threeri strs tess were conduct : the stress was decreasin pimary co regons of creep at 347.5 K and the str s w decasedprict 27 K. The results demonstrate the effects of structure and temperature on theess endence of the creep rate. The trends in the cr ep as arcomplicate nd show that recovery takes place. The experimental results re compared with Friedel's theory for crossslip, the expementdennergyor anstriton bg in god agrement th t theoreical eimatropod by Stroh. (Author)
