EFFECT OF ROLLING CONTACT FATIGUE ON THE ELASTIC-PLASTIC RESPONSE OF HADFIELD STEEL
Original language description
zpevnění.Instrumented indentation tests were performed to study the dynamic hardening od Hadfield steel in dtifferent states of rolling-contact proces. The influence of explosion hardening, as a prospective way to improve the wear resistance of Hadfield steel, was included in the test. Each step of the degradation process was simulated using the special rolling contact stand at a defined loading condition. The measured hardness gradient of loaded surface layers displayed the depth and intensity of the induced changes. Martens hardness was measured in thus identified layers for each representative state of material. The elastic-plastic capacity of the surface layer was evaluated as a ratio elastic to the global energy of indentation. The metallography evaluation, focused on the contact surface, documented an increase of elastic response as a result of the dislocation hardening process.
