ABSTRACT

The principles which govern heat treatment of metals and alloys are applicable to both ferrous and nonferrous alloys. However, in practice there are sufficient differences to make it convenient to emphasize as separate topics the peculiarities of the alloys of each class in their response to heat treatment. For example, in nonferrous alloys, eutectoid transformations, which play such a prominent role in steels, are seldom encountered, so there is less concern with principles associated with time-temperaturetransformation diagrams and with martensite formation. On the other hand, the principles associated with chemical homogenization of cast structures are applicable to many alloys in both classes. Diffusion Process The diffusion process is involved in nearly all heat treatments for nonferrous alloys. Common treatments include:

• Annealing after cold working
• Homogenization of castings
• Precipitation hardening treatments
• Development of two-phase structures
