Automated scanning electron microscopy (SEM) analysis of inclusions is playing an increasing role in the evolution of advanced steel grades. An area where automated inclusion analysis is lacking is with respect to the accurate characterization of duplex or multi-phase inclusions. Presently, analysis of multi-phase inclusions involves the collection of x-rays from a single or multiple points on an inclusion. These results lack specificity needed to provide an "accurate" identification of the type of inclusion and thus can be misleading. Recent improvements in automated SEM analysis enable intelligent decisions to be made regarding the detection, analysis and reporting of multi-phase inclusions.
