Abstract: A method of thermal treatment of components. The optimum thermal amplitude of the components at which the phase transformation kinetics of the components is maximum is determined by subjecting samples of the components to cyclic thermal processing at various thermal amplitudes by maintaining the upper temperature constant and varying the lower temperature. A thermal amplitude which is higher than the optimum thermal amplitude is selected. The components are subjected to cyclic thermal processing at the thermal amplitude selected above to achieve near uniform phase transformation kinetics of the components across their crosssection. The components are cooled down to room temperature to obtain components with near uniform microstructure and properties.
