Abstract
Friction stir processing experiments are conducted on aluminum alloy 5083 plates to enhance the surface integrity by introducing an ultrafine-grained surface layer. Microstructural analyses are carried out using optical microscopy to characterize the grain structures under various conditions. Within the produced surface layer, equiaxed ultra-fine grains are observed due to dynamic recrystallized during FSP. The grain size is reduced from 40μm to a submicron level for the FSP rotational speed of 800rpm. The hardness is increased to a peak value of 151 HV, which is higher than that of the unprocessed area by 50%.
