| Abstract: | For the problem of higher yield and tensile ratio of tempered Q420qE heavy plate,the microstructure transformation of Q420qE steel at different tempering temperature has been studied,influencing law of precipitation in the course of different tempering process on the yield and tensile ratio has been revealed,an appropriate tempering process in line with actual production condition at the site raised and successfully applied in actual production. |
| Keywords: | Tempering process Precipitates Yield and tensile ratio |
