The invention provides a light high-yield-strength aluminum alloy hub and a forging process thereof, and relates to the field of aluminum alloy hubs. The forging process of the light high-yield-strength aluminum alloy hub comprises the steps that raw materials are added into a smelting furnace to be melted, inert gas is introduced, the raw materials are poured into a mold to be cast into a first aluminum bar, preheating, pre-forging, forming forging, finish forging, deburring and heat treatment are conducted, the spoke is obtained, and the rim and the spoke are welded through friction stir welding. And the aluminum alloy hub with light weight and high yield strength is obtained. By refining the structure in the aluminum bar, the plasticity and toughness of the aluminum alloy are improved, the defects of impurities, bubbles and the like are avoided, gaps are finer, the density is higher, the interaction force between material molecules is stronger, the toughness is high, the prepared aluminum alloy hub is lighter, and the mechanical strength, the processability, the corrosion resistance and the yield strength of the aluminum alloy hub are improved.

    本发明提供一种轻质高屈服强度的铝合金轮毂及其锻造工艺,涉及铝合金轮毂领域。该轻质高屈服强度的铝合金轮毂的锻造工艺,包括将原料加入熔炼炉中进行熔化,通入惰性气体,倒入模具浇铸成第一铝棒,预加热,预锻,成型锻,终锻,去毛边,热处理,得到所述轮辐,将所述轮辋和所述轮辐通过搅拌摩擦焊焊接即可,得到轻质高屈服强度的铝合金轮毂。通过使铝棒中组织细化,增加铝合金的塑性和韧性,避免杂质、气泡等缺陷,间隙更细、密度更高,材质分子之间相互作用力更强,韧性高,制备的铝合金轮毂质量更轻,提高铝合金轮毂的机械强度、加工性能和耐腐蚀性能以及屈服强度。
