用计算机图象分析技术研究了夹杂物尺寸对实验钢中Ⅲ型MnS夹杂物热轧变形行为的影响。研究表明，直径小于5μm的夹杂物的变形。是尺寸相关的，较小的夹杂物变形较小。可以观察到完全未变形的夹杂物，但不可能精确地确定或预测在通常遇到的机械加工条件下，低于该尺寸的夹杂物不会发生变形。讨论了尺寸效应与夹杂物/基体界面能的关系。鉴于在分析中使用的统计方法的重要性，与所获得的结果有关，所采用的定量金相技术在附录中概述。
The influence of inclusion size on the deformation behaviour of Type III MnS inclusions in an experimental steel during hot rolling has been investigated using an image analysing computer. It has been shown that the deformation of inclusions of less than 5μm dia. is size dependent, with smaller inclusions being less deformed. Totally undeformed inclusions can be observed, but it has not been possible to determine or predict precisely the size below which inclusion deformation will not occur with normally encountered conditions of mechanical working. The relationship between the size effect and the inclusion/matrix interfacial energy is discussed. In view of the importance of the statistical method used in the analysis in relation to the results obtained, the techniques of quantitative metallography employed are outlined in an appendix.
