    Abstract: A method of heat-treating a workpiece includes generating an initial heating portion and a subsequent sustaining portion of an irradiance pulse incident on a target surface area of the workpiece. A combined duration of the initial heating portion and the subsequent sustaining portion is less than a thermal conduction time of the workpiece. The initial heating portion heats the target surface area to a desired temperature and the subsequent sustaining portion maintains the target surface area within a desired range from the desired temperature. Another method includes generating such an initial heating portion and subsequent sustaining portion of an irradiance pulse, monitoring at least one parameter indicative of a presently completed amount of a desired thermal process during the irradiance pulse, and modifying the irradiance pulse in response to deviation of the at least one parameter from an expected value.

    Abstract: A method involves increasing a temperature of a workpiece over a first time period to an intermediate temperature, and heating a surface of the workpiece to a desired temperature greater than the intermediate temperature, the heating commencing within less time following the first time period than the first time period. Another method involves pre-heating the workpiece from an initial temperature to an intermediate temperature, and heating a surface of the workpiece to a desired temperature greater than the intermediate temperature by an amount less than or equal to about one-fifth of a difference between the intermediate and initial temperatures. Another method involves irradiating a first side of the workpiece to pre-heat the workpiece to an intermediate temperature, and irradiating a second side of the workpiece to heat the second side to a desired temperature greater than the intermediate temperature.

    Abstract: A first heat-treating method involves monitoring at least one thermal efficiency parameter associated with an irradiance system configured to produce an irradiance flash incident on a surface of a workpiece, and automatically updating control information used by the irradiance system to produce the irradiance flash, in response to the monitoring of the thermal efficiency parameter. A second method involves predicting a heating effect of an irradiance flash to be incident upon a surface of a workpiece, in response to a measurement of a heating parameter of the surface, and pre-adjusting the irradiance flash, in response to the predicted heating effect. A third method involves measuring a temperature of a surface of a workpiece during an initial portion of an irradiance flash incident on the surface, and controlling a power of a remaining portion of the irradiance flash, in response to the temperature.
