Abstract:

The mechanisms of wear upon sliding over a fixed abrasive of high-carbon (0.83-1.84 wt\% C) steels that were subjected to quenching in water (790-1200degreesC), cold treatment (-196degreesC), and tempering (75-700degreesC) have been studied. The resistance of the steels to fracture under the conditions of microcutting (corundum-abrasive wear) and plastic edging (flint-abrasive wear) was found to be affected by the amount of retained austenite and carbon concentration in martensite. When the mechanism of plastic edging is realized, the negative role of enhanced brittleness of high-carbon (more than 1\% C) martensite manifests itself to a much greater extent. The presence of 60-70 vol\% retained austenite in quenched hypereutectoid steels may have both positive (under the conditions of microcutting) and negative (under the conditions of plastic edging) influence. A beneficial effect of metastable retained austenite on the wear resistance of the steels subjected to quenching and low-temperature tempering has been revealed. The effect of primary excess cementite (in amounts to 11 wt\%), graphite inclusions, grain size, and the degree of coalescence and volume fraction of tempering-induced carbides on the abrasive wear resistance has been considered. Structural changes in the steels upon wear were studied by electron microscopy, X-ray diffraction, and metallography.
