Dislocation-diffusion mechanism of high-temperature healing of the cracks in crystals under loading
The regularities of disc-like voids (cracks) healing in polycrystalline copper samples under conditions of uniaxial compression at 600°C were experimentally studied. The theory of crack healing by diffusion-dislocation mechanism was developed. Comparing the experimental data with the theoretical dep...
