| 1 | Processing of Ultralow Carbon Pipeline Steels with Acicular Ferrite显示文摘Acicular ferrite microstructure was achieved for an ultralow carbon pipeline steel through the improved thermomechanical control process (TMCP), which was based on the transformation process of deformed austenite of steel.Compared with commercial pipeline steels, the experimental ultralow carbon pipeline steel possessed the satisfied strength and toughness behaviors under the current improved TMCP, although it contained only approximately 0.025% C, which should mainly be attributed to the microstructural characteristics of acicular ferrite. | FurenXIAO MingchunZHAO YiyinSHAN BoLIAO KeYANG | 2004 | Journal of Materials Science & Technology2004，20，6： | 4 |
| 2 | Effect of Hot Deformation on Pearlite Transformation of 86CrMoV7 Steel显示文摘The continuous cooling transformation (CCT) diagrams of 86CrMoV7 steel samples including hot deformed and not hot deformed were constructed by dilatometry, metallography and transmission electron microscopy (TEM). The results showed that hot deformation accelerated pearlite transformation and fine pearlite microstructure. Moreover,the undissolved carbides became the nucleating sites of pearlite, accelerated pearlite formation and fine pearlite if the steel had been deformed at high temperature. In contrast, undissolved carbides did not make any influence on pearlite transformation if the steel had not been deformed at high temperature. | MingGAO HongxingCU FurenXIAO BoLIAO GuiyingQIAO KeYAXG YiyinSHAN | 2004 | Journal of Materials Science & Technology2004，20，1： | 0 |
