Chapter 2 Basic Heat Treatment - NAVY BMRThe heat treatment of ferrous metals (metals with iron) usually consists of annealing, normalizing, hardening, and/or tempering. Most nonferrous metals can be annealed, but never tempered, normalized, or case hardened. To successfully heat treat a metal, you need to have the proper equipment with close control over all factors relevant to the heating and cooling.Heat Treatment and Properties of Iron and Steelcerning the heat treatment of iron and steel and for directions and explanations of such processes.

Austenite has a higher solubility limit for carbon and alloying elements, and the carbides will dissolve into the matrix to some extent. In this way the matrix acquires an alloying con-tent of carbide-forming elements that gives the hardening effect, without becoming coarse grained.

This heat energy allows carbon atoms to diffuse out of the distorted lattice structure associated with martensite, and thus relieve some of the internal stresses.Some results are removed in response to a notice of local law requirement.

The final heat treatment is followed by cold drawing involving limited deformation. Appropriate further processing allows a certain degree of cold forming (e.g. bending, expanding).

Heat Treating Overview Heat treating, as the name implies, is a series of treatments in which heat is used to alter the properties of a metal or alloy. Because time at temperature is also important, heat treatment can be further defined as a series of time-temperature treat-ments. Heat treatments are STEEL GROUPS EN 10027-2:2003STEEL GROUPS .
