Nicholas Careau ME 5310 Prof. Shivkumar 12/14/09 HW Assignment 10 Problem 13.7 a) Process Anneal: a low temperature heat treatment used to eliminate all or part of the effect of cold working in steels b) Austenitizing: Heating a steel or cast iron to a temperature where homogeneous austenite can form. Austenitizing is the first step in most of the heat treatments for steel and cast irons. c) Annealing: In cast irons, annealing is a heat treatment used to produce a ferrite matrix by austenitizing, then furnace cooling. In steels, annealing is a heat treatment used to produce a soft, coarse pearlite by austenitizing, then furnace cooling. d) Normalizing: A simple heat treatment obtained by austenitizing and air cooling to produce a fine pearlitic structure. This can be done in steels and cast irons. e) Quenching: a process used to harden most steels which is typically done through submerging a hot metal into a cool liquid to produce a rapid change in the temperature of the metal.
