“…To improve the surface integrity of structural components made of aluminum alloys, SPD has been applied successfully [1-3, 5, 6, 21-34]. Basically, the studies aimed at evaluating the effectiveness of roller burnishing on the obtained roughness and accuracy [1-3, 5, 6, 28, 29], as well as of deep rolling [27,30,31] for increasing the fatigue strength.…”
