AB - The fast evolving temperature fields at the surface of induction-heated parts were measured by a contactless, optical method based on temperature-sensitive lacquers recorded with a high-speed imaging system. The positions of specific isotherms over time were precisely measured by image analysis. A 4340 steel cylinder and two spur gears of the same material were investigated. One spur gear was treated at high frequency, and the other one at simultaneous dual frequency. In both cases, the temperature started to rise at the root of the teeth and then expanded along the flanks. The heating rates were higher at the tips than at the roots for both treatments, with higher values for the dual-frequency treatment. The layer of transformed material was similar for both treatments, but the transformation temperature varied greatly. It was found to be 50-100 °C higher than the equilibrium values, depending on the local heating rate.
