Sažetak
Heat transfer mechanisms at quenching in evaporable liquid quenchants, and at high pressure gas quenching in vacuum furnaces, are described. In three different Liscic probes, the temperature gradient method is used to evaluate the cooling intensity at quenching in laboratory and workshop environments. Calculation of the heat transfer coefficient is based on temperatures measured in time at a near-surface point in the probe. After smoothing, they are used as an input for the one-dimensional heat conduction equation. The surface heat flux density is calculated to reproduce the input temperature, by finite differences or finite volumes.
