- Abstract
In the present work, the formation and growth of Al-Ti-O complex inclusions in the steel after SiMn and Ti deoxidation is systematically investigated. The evolution with time of the size, composition and morphology of the Al-Ti-O complex inclusions were studied. After adding 70TiFe alloy, the inclusion composition changed from Si-Mn-Al to Ti-Al-O-N. The growth of the inclusions after a deoxidation time of 30 s is mainly controlled by turbulent collisions. The three-dimensional morphology and shape factor of the inclusions is determined to research the growth pattern of Al-Ti inclusions.
