Mitigation of Cu-Induced Sensitization in Steel Wire Rods via Optimized Heat Treatment

Steel wire rods are crucial for reinforcing automobile tires, but sensitization in secondary steel limits their use in tire manufacturing. This study explores the impact of Cu migration to grain boundaries during heat treatment, exacerbating sensitization. Authors propose a novel heat treatment approach designed to diffuse Cu away from austenite grain boundaries, thereby mitigating sensitization effects. The results are compared to those from conventional industrial processes, highlighting the effectiveness of the proposed method in improving the mechanical properties and microstructure of secondary steel for tire manufacturing.
