A recommended practice for preparation and evaluation of steel specimens for automatic inclusion assessment was developed. The polishing procedure involved the use of diamond abrasives on rotating paper laps. This technique preserved the true morphology of the non-metallic inclusions. Evaluation of a properly prepared sample was accomplished using the sensitive tint condition of Differential Interference Contrast Microscopy.
