| 中文摘要 | A finite element analysis was performed to study the strain induced transformation rolling process through which ultra-fine-grain steels were produced. Within the surface layer of the specimen, where ultra-fined grains were found, high strain and severe undercooling were found to coexist during hot deformation. It is proposed in this paper that the ultra-refinement was caused by the deformation of austenite in a severely undercooled state. To verify the grain refinement potential of severe undercooling thermomechanical treatment, hot compression experiments were done on a Gleeble1500 thermo-mechanical simulator. Severe undercooling was obtained by cooling the specimens at very high cooling rate before deformation. Metallographic observations showed that ultrafine grains could be obtained at a true strain of 0.9 provided that undercooling was higher than 200 K. (C) 2002 Published by Elsevier Science B.V. |
