Free Webinar! 21 November, 22:00 (AST) / USING METALLOGRAPHY TO UNDERSTAND HEAT TREATMENT RESULTS
How does processing and heat treatment procedures alter microstructures? This lecture defines and illustrates with multiple examples to show how processing and heat treatment procedures alter microstructures. Examples are given of improper microstructures that caused component failures. Topics covered include: as-rolled microstructures, annealing, normalizing, isothermal transformations, continuous cooling transformations, under and over-austenitization, prior-austenite grain size control, solution annealing, surface treatments (carburizing, carbo-nitriding, nitriding), retained austenite, and problem microstructures. Examples illustrate how different etchants for steels reveal such structures, either more [...]
