| 摘 要： | 文章研究了脆性相变对高锰钢组织性能的影响,结果表明无论是铸态或已水韧处理的高锰钢工件,在加热过程中都有一脆性相变区间,高锰钢在这个温度区间加热保温,因脆性相析出而使组织严重恶化,机械性能显著下降。高锰钢脆性相变不仅与加热温度有关,而且与保温时间长短有关。在脆性相变区加热保温时间越长,脆性相析出越多,对性能影响越严重,可见在高锰钢铸件加热过程中,严格控制脆变行为对提高高锰钢热处理质量,进而延长产品的使用寿命十分有益。

| Abstract: | The paper studies the effects of brittleness phase transformation on microstructure and performance of high manganese steel. Experimental results show that a brittleness phase transformation region exists in the heating course whatever in cast or water annealing for high manganese steel workpieces, the mechanic performance of high manganese steel will decrease dramatically due to precipitation of brittleness phases while this steel is heated and kept in this temperature interval. The brittleness phase transformation is relate to not only heating temperature, but also to heating time. The longer the heating time in the brittleness phase transformation interval is, the more brittleness phases are precipitated, and the effects on performance of materials will be serious. Therefore it will enhance the heat treatment quality of high manganese steel and prolong the service life of productions that controlling strictly the brittleness transformation in the heating course of this material. |
