文摘

Numerical simulation of deformed layer and residual stresses induced by surface mechanical attrition treatment was studied. Experimental coverage and Almen intensity of surface mechanical attrition treatment were successfully characterized. The numerical coverage was in agreement with the experimental surface coverage. The coverage of surface mechanical attrition treatment was found to follow the well-known Avrami model. This study has established foundations for the direct comparison of samples with different parameter sets of the treatment.
