| 图5 590 MPa级高强钢成形金属连续冷却转变(CCT)曲线 |
| Fig.5 Continuous cooling transformation (CCT) curves of 590 MPa grade high strength steel deposited metal (M—martensite, B—bainite, F—ferrite, P—pearlite, Ms—martensite transformation start temperature, Mf—martensite transformation finish temperature, Ac1—start temperature of pearlite transformation into austenite during heating, Ac3—final temperature of ferrite transformation into austenite during heating, t—cooling time. Green line represents the starting line of ferrite transformation, purple line represents the starting line of bainite transformation, orange line represents the starting line of pearlite transformation, red line represents the final line of bainite transformation, and blue-green line represents the final line of pearlite transformation) |
