摘要
通过金相分析,简要介绍了轴承钢GCr15碳化物不均匀性的表现形式、分级判定、形成原因及应用危害;结合实际钢种CCT曲线及碳化物析出规律,探讨并提出了控制轴承钢GCr15碳化物不均匀性适宜的工艺路径与措施。
Combining the metallographic analysis,this article briefly introduces the manifestation,grading judgment,causes and application hazards of carbide nonuniformity Bearing Steel GCr15. By analyzing the CCT curves and the separation principles of carbide,appropriate process and measures for controlling nonuniformity of carbide in Bearing Steel GCr15 were also discussed and proposed.
