Unformatted text preview: Eutectic if it has liquid at the top its eutectoid Time Hardness Red = over aging but a low temp The blue is a higher temp but low hardening Know pearlite. If you take a steel from high temp (gamma) to a bucket of water you'll get marten site. Which is hard and brittle. You then heat it (called tempering) to fix the brittleness. Process Anneal Annealing- From gamma to furnace cool Normalizing- form gamma to air cool Spheroid zing heat to below Eutectoid. Forms round spheres Stainless steel add chromium oxide to prevent corrosion...
