| Abstract: | The deep cryogenic treatment for relief of residual stresses in aluminum alloy is introduced and the stress state in deep cryogenic treatment process is analyzed in the paper. The conclusion that the residual stresses elimination mechanism are stress reversal, grain refinement and interatomic kinetic energy shifting. |
