| 摘要 | Based on the effect of accelerating cooling on the microstructure and properties of thermo-mechanical control process (TMCP) steel, we proposed to adopt this method for improvement of heat affect zone (HAZ) toughness of X70 pipeline steel. The results of simulated experiment and actual weldment indicate that at appropriate accelerating cooling rate the M-A constituent in HAZ is reduced obviously in amount and replaced by tough austenite films. Coarse bainitic sheaves were obtained when jetting water directly to the sample and the toughness is not improved. Accelerating cooling with appropriate cooling rate is a simple and efficient method to improve the HAZ toughness. |
