Course content

Heat treatment of plain carbon and alloy steels: Annealing, normalising, hardening and tempering.? Effect of using different cooling media.? Hardenability measurement by Jominy test.? Surface hardening by thermochemical treatments (carburizing / boriding).? Quantitative metallography to evaluate ceramics, inclusion count, case depth and reinforcement in composites.? Tutorials for introducing important aspects of heat treatment.
