| 英文摘要 | The coarse primary carbides in high-carbon alloy steels can significantly impair their overall performance. Reducing and refining the primary carbides efficiently are always of great significance in material processing. Here, an innovative approach - the selective microzone remelting (SMR) method, is proposed to dramatically reduce and refine the coarse primary carbides. The method is achieved by utilizing an electric current and is facilitated with the substantial difference in electrical resistivity between carbides and the matrix phase. When a sample contains massive coarse primary carbides is subjected to an electric current, the high electrical resistivity of carbides leads to the selective remelting of local carbides before the sample reaches solidus temperature during heating while during cooling the big difference in electrical resistivity suppresses the carbides formation but promotes the austenite nucleation and growth. This mechanism has been validated through the successful treatment of M50 bearing steel, in which the large-sized blocky primary carbides were eliminated completely, leaving only small-sized eutectics with extremely thin lamellas. Besides, the microporosity in the as-cast sample has also been reduced significantly via SMR treatment. These studies demonstrated that the proposed SMR treatment can be a promising method to reduce and refine coarse precipitates formed during solidification in various alloys. |
