Sažetak
A quench probe, based on the Temperature Gradient method was used to measure and record cooling curves when quenching real axially symmetric workpieces of any complex shape in liquid quenchants. Calculation of relevant heat transfer coefficients is based on the cooling curve measured just below surface of the cylindrical probe of 50-mm diameter. A two-dimensional computer program, based on the cooling time from 800°C to 500°C (t8/5), and the Jominy hardenability curve of the steel grade in question, is used to predict the hardness distribution within the whole volume of the workpiece, all at once, which is a unique feature of this method.
