Influence of Increased Tramp Element Contents on Wetting Conditions and Deformation Behavior of Nonmetallic Inclusions in Medium-Carbon Steels

A key point for the transformation of steel industry is increasing the recycling rate of steel using electric arc furnaces. However, tramp elements such as copper, molybdenum and tin accumulate over the recycling cycles. While their influences on hot shortness, shift of transformation points, or hardness are in focus of research since decades, the interactions between tramp elements and nonmetallic inclusions remain mostly unknown. Therefore, this work emphasizes their influence on a change in wetting behavior or surface tension in liquid steel as well as their effect on deformation behavior or hardness of nonmetallic inclusions and the surrounding steel matrix.
