高端制造业的发展在很大程度上取决于易切削钢的质量。特别是MnS夹杂物的特性是提高高品质易切削钢质量的关键问题。以往对MnS夹杂物形态演化机制的研究主要集中在二维定性观察和趋势分析上。利用Micro-CT对钢中MnS夹杂物的形貌进行了观察。对MnS夹杂物的体视学、尺寸和形态进行了详细表征，以研究钢样轧制过程中夹杂物的各向异性和形态演变。基于对MnS夹杂物尺寸比的统计分析，提出了一种定量描述钢中夹杂物各向异性的各向异性指数。该指标可用于定量评价钢中MnS夹杂物的各向异性。根据MnS夹杂物在轧制过程中的形态演变，定义了形状因子φ，定量研究了MnS夹杂物的三维形态。此外，通过对轧制前后一系列典型MnS夹杂物的观察，探讨了轧制过程中的遗传性。
The development of the high-end manufacturing industry is largely dependent on the quality of free-cutting steel. In particular, the characteristic of MnS inclusions is a key issue in the improvement of the quality of high-quality free-cutting steel. Previous studies on the mechanism of morphological evolution of MnS inclusions have mainly focused on two-dimensional qualitative observation and trend analysis. In this study, the morphology of MnS inclusions in steel was observed using Micro-CT. The stereology, dimensions, and morphology of MnS inclusions were characterized in detail to investigate the anisotropy and morphology evolution of inclusions during the rolling of steel samples. An anisotropy index was proposed based on the statistical analysis of the dimensional ratios of the MnS inclusions to quantitatively describe the anisotropy of inclusions in the steel sample. This index could potentially be applied to the quantification of the anisotropy of MnS inclusions in steel products. The shape factor, φ, was defined to quantitatively investigate the 3D morphology of MnS inclusions, based on their morphology evolution during rolling. In addition, the heredity during rolling was discussed based on the visualization of a series of typical MnS inclusions before and after rolling.
