| 摘 要： | 针对GCr15轴承钢正常淬火组织中的黑白区及过热淬火组织中明暗相间的带状组织进行了论述。认为，黑白区与带状组织的出现是由于存在不同含铬量的合金渗碳体的偏聚和过热淬火造成的，可以通过生产工艺的优化进行控制。

| Abstract: | Based on the analysis of numerous researches of the cause for regions of black and white in the normal quenching structures and the zonal structures in overheating quenching structure, this article conclude that the essential cause for such structures is the partial centralization or zonal structures exist in the alloy cementite with different chrome contents, and which can be controlled via the optimization of practical production techniques. |
