Unformatted text preview: Heated then quenched in water bath, then re heated to specific temperature and held for specific time. then cooled to room temperature what are three of the constituents that make up a microstructure composition, grain, phase concepts true false all steels need to be heated to the same temp for heat treatment irrespective of its compostition F tempering is a combination of quenching and nomalizing T quenching can use either water or oil as cooling media T annealing is very inexpensive process F cutting tool steels have low carbon percentage F annealing produces a martensitic structure F pearlite is a product of air cooling after heating to a specific temp T...
