Symposium Gas/Metal Reactions, Diffusion, and Phase Transformation during Heat Treatment of Steel
Organizer(s) Daniel S. Baker, General Motors
Scope Ferrous metallurgy continues to evolve through advances in alloy development and processing. Heat treating is becoming a required manufacturing step for many ferrous products from sheet steels used for automotive body in white construction to bar steels used for gears and shafts to plate steels used for wear resistance applications or pipe and tubes.
Heat treating techniques include annealing, case hardening, precipitation strengthening, quenching and tempering. During heat treating processes, various atmosphere/steel reactions occur at the part surface, along with diffusion/phase transformation within the steel part. Added carbon and nitrogen through carburization, nitriding, or carbonitriding can greatly affect the response to heat treatment and the resulting microstructure and residual stresses. Research results from modeling to experimentation techniques used to understand the interactions, reactions, diffusion and phase transformation processes are expected.
This symposium encourages reports from the entire heat treat industry, from equipment suppliers to heat treaters to final users of the parts along with academia to communicate and share their new findings. Topics anticipated include, but are not limited to:
• Development of novel heat treatment technologies
• Materials science for heat treatment process design
• Numerical simulation of gas/metal reactions, diffusion and phase transformation during heat treating
• Improvements of heat treatment response through re-designing steel composition
• Microstructural study of steel during heat treatment processes
• Study on the relationship between microstructure and mechanical properties of heat treated steel
• Effect of heat treatment on the residual stresses imparted due to phase transformation or externally applied forces
• Effect of heat treatment atmosphere on carburization/nitriding/decarburization/oxidation
