| Abstract: | A new technology has been used for the die forging process of aluminium alloy hub of heavy automobile. By selecting raw material with low content of Fe and H 2, adopting high die forging temperature, high solution heat treatment temperature and high ageing temperture, the property of forging has been improved greatly with a rise of 30% in strength, 40% in hardness and 50% in elongation. In this paper, the details of the process were presented, and the influence factors and the strengthening mechanism of forging property improvement were analyzed. |
