Abstract
The paper studies the structure and morphology of the treating zone surface of cast aluminum alloy AlSi12 after 1-4 passes with a friction stir tool. The studies show that after all four passes, the surface of the tool exit zone has traces of material tearing out along the edge of the pin, but the overall appearance of the machining surface improves. The structure after four passes with the tool is dominated by smaller and more rounded particles, while after one pass there is a large number of elongated particles. Friction stir processing leads to improvement of material plasticity by up to 2.5 times and ultimate tensile strength value by 9-10%.
