ABSTRACT:
A method for heat treating an aluminum part is provided. The method includes heat treating the aluminum alloy part with direct radiation from a source of infrared energy until the part attains a desired state of heat treatment. The method and apparatus further include monitoring of the part and controlling the intensity of the radiation source through proportional control in response to the measured temperature.
