چکیده انگلیسی
Despite numerous investigations on gradient temperature rolling (GTR) and its influence on grain refining, no research exists on appropriate cooling after GTR, which is important in the microstructural control. This work focuses on the effect of final microstructure on heavy-plate properties and microstructural evolution during different rolling and cooling processes. GTR and uniform temperature rolling (UTR) were applied to E40-grade heavy plates. GTR plates were maintained at 1073Â K at their surface and 1473Â K at their core. After rolling, experimental plates were cooled at a series of rates. Their microstructure and mechanical properties were studied. The plate prepared using GTR and air cooling had the best integrated property because of its uniform and fine ferrite microstructure. The GTR plate strength increased gradually with a corresponding decrease in toughness as the cooling rate increased. The uniform temperature rolling plate cooled in water exhibited the worst mechanical properties.
