Results and Conclusions:
The parts were heated in two different coils for comparison. The plate concentrator coil provided a better heat time and concentrated the heat marginally better than the oblong coil. Part positioning in the coil is very important in this application and will require fixturing for accurate repeatability. The time it took to move the part from the coil to the quenching oil varied and allowed the temperature to drop from the peak temperature reached. The exact quenching temperature for each sample part is unconfirmed. Sample number 4 was used as a tuning/test sample and was heated several times but not quenched. At the end of the testing, it was heated using the pancake concentrator coil and then quenched in oil.
