| 摘要 |
The present invention comprises an improved process for the preparation of aluminum base alloys containing magnesium and silicon in wrought form, and particularly as tread plate which includes the steps of casting, homogenizing, hot rolling within a critical temperature and time range and cooling at a rate greater than a critical rate and before a critical delay time after said hot rolling step. The resulting product can be artificially aged without the need for a separate solution heat treatment and possesses improved tensile properties, surface appearance and corrosion resistance.
