Achieving desired properties in bainite steels with MA islands demands understanding the affect of processing conditions and composition on their size and morphology. Generally, this understanding is gained by studying the change in the size and morphology of the MA islands with composition and the processing conditions. In the present work, around 8500 MA islands dispersed across of approximately 1500 bainite microstructures are investigated to comprehend the influence of composition and heat treatment cycle on the geometric features. The geometric features considered in this study include polygon area metric, compactness and aspect ratio. A thorough statistical analysis of these features across bainite steels of different compositions and processing conditions unravel that, though there are minor changes, no characteristic variation is introduced in the size and morphology of the MA islands. In other words, the distribution of the various forms of MA islands are almost identical in bainite steels of different chemistry and heat treatment, thereby indicating the inadequacy of geometric features in explicating the affect of processing conditions on microstructure.
