摘要/Abstract

摘要： 通过光学显微镜、扫描电镜、拉伸试验机和冲击试验机等研究了00Cr23Ni12Mn5Mo2N奥氏体不锈钢不同制备工艺下的显微组织以及经高温均匀化后表面和心部的力学性能、断口形貌等。结果表明,试验钢经1190 ℃保温24 h的高温均匀化处理可以有效消除σ相,切实提高试验钢的高温性能,为锻造提供有利条件。试验钢经高温均匀化后,再经两镦两拔的方式锻造成形,并控制锻造温度在1210~950 ℃,可有效改善心部变形不充分的问题,表面和心部动态再结晶较完全,组织均匀细小,表面和心部晶粒度均可达到6级以上。试验钢锻后表面和心部性能均较为优异,表面的抗拉强度、伸长率、断面收缩率、硬度及77 K冲击吸收能量分别为821 MPa、41.0%、65.0%、252 HBW和49.1 J,心部强度和硬度略低于表面,但塑韧性相对较好。

Abstract: Microstructure of the 00Cr23Ni12Mn5Mo2N austenitic stainless steel under different preparation processes, as well as the mechanical properties and fracture morphology of the surface and core after high temperature homogenization, were studied by means of optical microscope, scanning electron microscope, tensile testing machine and impact testing machine. The results demonstrate that high temperature homogenization at 1190 ℃ for 24 h can effectively eliminate the σ-phase, effectively improve the high temperature properties of the tested steel and provide favorable conditions for forging. After high temperature homogenization, by forging and forming with two upsetting and two drawing methods, and controlling the forging temperature between 1210-950 ℃, the problem of insufficient deformation of the core can be effectively solved, the dynamic recrystallization of surface and core is complete, the microstructure is uniform and fine and the grain size of the surface and core can both reach grade 6 or above. The surface and core properties after forging are excellent. The tensile strength, elongation, percentage reduction of area, hardness and impact absorbed energy at 77 K on surface of the tested steel are 821 MPa, 41.0%, 65.0%, 252 HBW and 49.1 J, respectively, while the strength and hardness of the core are slightly lower than that of the surface, and the plasticity and toughness of the core are better.
