| Abstract: | Cryogenic treatment of high-speed steels may effectively helps transforms form retained austenite into martensite and precipitate fine carbides, which brings better comprehensive mechanical properties to tools. The service life of a tool made of high-speed steels after Cryogenic treatment is prolonged obviously. |
