| 摘 要： | 本文阐述了钢中非金属夹杂物的形成、分类及来源，以及非金属夹杂物数量、尺寸对钢材性能的影响，对评判非金属夹杂物的国家标准GB/T 10561新旧两个版本即2005版和1989版进行比较，分析了氮化物等沉淀相的特性及其对钢材的强化作用，阐明了2005版标准中关于将氮化物、碳化物、碳氮化合物、硼化物定性描述为沉淀相而不作为非金属夹杂物的评判是适宜的。

| Abstract: | This paper describes the formation , classification and source of non -metallic inclusions in steel , and the influence of their quantity and size on the performance of steels .It compares the commons and differences between the new National Standard GB /T10561 2005 version with the old 1989 version for evaluating non-metallic inclusions , and analyzes the characteristics of the precipitated phase such as the nitride and the strengthening effect to the steel , and explains that it is appropriate to evaluate nitrides, carbides, hydrocarbons and boride as precipitated phase not as non -metallic inclusions. |

| Keywords: | Non-metallic inclusions Precipitated phase Evaluate |
