| Abstract: | Investigates the influence of medium-frequency induction tempering on the structure and properties of quenched and tempered 45Si2Cr reinforced bars. Experiments indicated that the induction-tempered microstructure shows a full transformation with stable properties and homogeneus cross-sectional structure and properties . Its machanical properties are able to meet the specification of the reinforced bars after patenting-tempering with its fine homogeniety.Therefore tempering by induction heating is proved replaceable for patenting-tempering. More than that, such as tempering process has advantages of saving energy and avoiding the lead pollution. |
