Abstract
In this study, two different heating methods have been used for the hot forging process of ANSI 1050 steel. Some specimens were heated by induction generator at 250 kW, 3.2 kHz up to a temperature of 1250 °C ± 5 °C in 5 minutes under ambient conditions via a continuous conveyor belt system. Other steel specimens were heated continuously in a conventional furnace up to a temperature of 1230 °C ± 40 °C at ambient conditions in 30 minutes. All specimens were subjected to Charpy, three-point bending, fracture strain, and hardness tests (surface and cross-section measurements). Almost all mechanical test results were better for the specimens heated by the induction generator and also appeared as more stable than those for the specimens heated by conventional furnace which varying some showed results. Grain growing was found in the microstructure of the conventional heated specimens. Induction heated specimens were heated more homogenously than the conventional heated specimens which is the reason for more stable results. © Carl Hanser Verlag, München Materials Testing.
