| 3 | Influence of cryogenic treatment on the wear characteristics of 100Cr6 bearing steel显示文摘A series of reciprocating wear tests were performed on the deep cryogenically treated and conventionally heat-treated samples of 100Cr6 bearing steel to study the wear resistance.The worn surfaces as well as the wear debris were analyzed by scanning electron microscopy.The improvement in wear resistance of the deep cryogenically treated samples ranges from 49% to 52%.This significant improvement in wear resistance can be attributed to finer carbide precipitation in the tempered martensitic matrix and the transformation of retained austenite into martensite.X-ray diffraction analysis shows that the volume fraction of retained austenite in the conventionally heat-treated samples is 14% and that of the deep cryogenically treated samples is only 3%. | R.Sri Siva D.Mohan Lal P.Kesavan Nair M.Arockia Jaswin | 2014 | International Journal of Minerals,Metallurgy and Materials2014，21，1： | 0 |
