摘要/Abstract

摘要： 采用组织表征、化学成分与EDS分析相结合的方法,系统研究了27SiMn钢液压支架柱头在加工过程中出现裂纹的失效机理。结果表明,柱头裂纹的起源与锻造过程中形成的折叠缺陷相关,裂纹沿分模面呈纵向扩展特征。在后续的淬火和回火处理过程中,该缺陷作为应力集中源,促进了裂纹的萌生。裂纹区域存在明显的S、P、W、Si等元素的偏聚现象,形成的复合夹杂物不仅增加了材料的脆性,还导致了穿晶-沿晶混合断裂模式的出现。此外,现行的淬火-回火工艺未能完全抑制贝氏体的形成,且未能有效消除元素偏析问题。建议通过改进模具设计,降低分模面金属流动阻力,有效抑制折叠缺陷的形成及元素偏析现象;同时,优化热处理工艺参数,在锻造工序后增设正火处理环节,以提升元素分布的均匀性。此外,提高淬火温度和冷却速率可有效遏制贝氏体转变。

Abstract: Failure mechanism of cracks in the hydraulic support column head of 27SiMn steel during processing was systematically studied by using a combination of microstructure characterization, chemical composition, and EDS analysis. The results indicate that the origin of the column head crack is closely related to the folding defects formed during the forging process, and the crack exhibits longitudinal propagation characteristics along the parting surface. In the subsequent quenching and tempering processes, this defect acts as a stress concentration center, promoting the initiation of cracks. There is a significant segregation phenomenon of S, P, W, Si and other elements in the crack area, and the formed composite inclusions not only increase the brittleness of the material, but also induce the occurrence of transgranular-intergranular mixed fracture mode. In addition, the current quenching and tempering process can not completely suppress the formation of bainite and effectively eliminate the problem of element segregation. It is suggested to improve the mold design to reduce the metal flow resistance on the parting surface, effectively to suppress the formation of folding defects and element segregation phenomena, simultaneously optimize the heat treatment process parameters and add a normalizing treatment step after the forging process to improve the uniformity of element distribution, and increase the quenching temperature and cooling rate to effectively suppress bainite transformation.
