Thesis Title: Thermomechanical Processing of Microalloyed Bar Steels for Induction Hardened Components

Abstract: Thermomechanical rolling of microalloyed steels has been shown to produce refined final microstructures in steel sheet and plate production. This project studies the effects of chemical composition and thermomechanical processing steps in preconditioning steel bars for subsequent induction hardening in order to improve both fracture toughness and fatigue life. Processing details are designed to investigate behaviors of microalloying additions either in solution, as fine precipitates formed in ferrite, and as coarse precipitates formed in austenite.
