Because time at temperature is also important, heat treatment can be further defined as a series of time-temperature treat-ments. heat treatments are used for a variety of purposes, the most important being to control the mechanical properties, especially hardness, ductility, strength, toughness, and internal is the resistance of a material to plastic indentation.
Oxide Dispersion Strengthening. With this powder metallurgy method, oxides such as yttria or alumina or metals that are strong oxide formers, such as tantalum, are added during the mechani-cal alloying step. They become uniformly distributed through the alloy and impart strength to the component.
