Abstract
The effect of friction stirs processing (FSP) on the fatigue life of a cast Al-7Si-0.6 Mg alloy at stress ratios of R = 0 and R = -1 was evaluated. Two types of specimen geometry were used for the FSPed condition, through thickness processed and partial thickness processed. at R = 0, the microstructural refinement enhanced the fatigue life by a factor of 15, whereas at R = -1 the improvement in fatigue life was 5-fold. in light of these observations, various closure mechanisms were examined. © 2009 Acta Materialia Inc.
