Microstructural evolution of copper clad steel bimetallic wire

▶ Co-deformation microstructure and hardness responses in two copper clad steel wires. ▶ Grain size discrepancy at the steel-copper interface, related to co-deformation. ▶ FEM used to quantify drawing stress gradients related to microstructure evolution. ▶ Characterized the texture responses as a function of draw and heat treatment. ▶ The hardness in steel variation related to work hardening and pearlitic structures.
