There hasn't been a better time than now to evaluate the quality and economics of heat-treating processes. Accelerated Austenitizing (AA) may provide a competitive edge needed in today's economic climate. Michael Hammond of Electroheat Technologies describes some of the benefits now possible with this process. Higher production rates, improved quality and lower distortion are the key benefits of Accelerated Austenitizing, (AA). Recent developments in AA with Simultaneous Dual Frequency (SDF) induction heating has provided inroads into producing higher quality microstructures at faster processing cycles and lower distortion results than conventional heat-treating processes. With the advent of using two frequency ranges, medium and high, the use of high flux intensity heating through uniform heating of nonlinear surfaces such as gears, sprockets, camshafts and other nonlinear complex surfaces has expanded.
