Abstract

A method has been developed for calculating the stresses and strains created during the quenching of railroad rails. The use of a generalized heat-conduction equation of the hyperbolic type made it possible to determine the oscillatory character of the changes in temperature, stress, and strain during the thermal shock that accompanies the initial stage of quenching. Another innovative feature of the mathematical model that was constructed is that it accounts for the kinetics of the transformations of austenite into pearlite and martensite during the quenching operation. The results obtained from calculations of the stresses formed during the bulk quenching of rails in oil agree satisfactorily with the experimental data.
