| 英文摘要 | Phase transition and defect relaxation behavior of a Fe-7Mn-0.1C medium manganese steel have been systematically studied mainly by using internal friction (IF) technique. From temperature-dependent IF curves in both heating and cooling processes, two relaxation IF peaks (the P-1 located at similar to 200 degrees C on heating and the P-2 at similar to 550 degrees C on cooling) and two phase transition IF peaks (the P-tr1 located at similar to 670 degrees C on heating and the P-tr2 at similar to 300 degrees C on cooling) were observed. The P-1 peak disappears when the cementite (theta) particles and/or retained austenite (gamma(R)) exist in the microstructure, and is associated with the Snoek-Ke-Koster re-laxation (SKK relaxation). The P-2 peak is suggested to be originated from grain boundary relaxation in austenite (gamma). The formation mechanisms of the P-tr1 and the P-tr2 come from reverse austenitic transfor-mation (RAT) and martensitic transformation (MT), respectively. In addition, the apparent asymmetry of the P-tr1, the variation of peak height, the difference between the P-tr1 and P-tr2 peaks, and the effect of IF studies on the mechanical properties are discussed in detail in the present work. These results provide a valuable reference for the design of high-performance medium Mn steels. (C) 2022 Elsevier B.V. All rights reserved. |
