EFFECTS OF PRODUCTION METHODS ON RESIDUAL STRESSES IN COMPLETELY QUENCHED RAILS

Complete quenching sets up high residual stresses in rails. Tempering lowers them while only slightly reducing rail hardness. Straightening after quenching and tempering again raises the residual stresses, making the rails prone to fracture along the neck. This is due to plastic deformation during straightening in the vertical plane, and to lower the residual stresses the maximum bending deflection should be limited. The increase in the residual stresses is then compensated by the high strength values of steel obtained by quenching.
