HEAT TREATMENT METHOD FOR ALUMINIUM HOT FORGING

摘要

The present invention relates to a heat treatment method for aluminium hot forging, comprising the steps of: a) producing a forged article by forging and trimming a heated starting material; b) raising the temperature to a temperature allowing solid solution treatment while residual heat remains in the forged article; c) subjecting the forged article, of which the temperature has been raised, to a solid solution treatment; and d) subjecting the forged article, which has undergone the solid solution treatment, to water cooling and an ageing treatment. The thus-configured present invention is a heat treatment method for aluminium hot forging in which the temperature of the forged article is raised to the solid solution treatment temperature and the forged article is subjected to a solid solution treatment without being air-cooled after hot forging, thereby giving the advantageous effect that the time needed to raise the temperature to the solid solution treatment temperature after air cooling is shortened and productivity is increased.
