The change of the dislocation structure of cold worked Mo single and polycrystals during reloading at T 2 ⪆ 350 K has been studied by HVEM. The structure change was found to proceed in three discernible stages: i. formation of obstacle‐free zones by local annihilation of existing dislocations, ii. appearence of large scale slip in these zones, iii. blocking of slip zones by the formation of dislocation cell structure.
