Non Equilibrium Heat Treatment
Non equilibrium conditions
Non equilibrium is when a reaction is not allowed to go to completion. An example is quenching
when a hot object is plunged into a bath of cool liquid, such as iced brine

Mechanical Behavior of Materials
Consider a metal rod fixed at one end.
At the other end a load can be applied
by some manner. When a small amount
of load is applied, if the length of the metal
rod was measured it wou

Few materials used in pure state gold, copper, platinum etc for electrical
properties or coatings.
Most materials consist of mixtures of elements. Can be two, or a binary
system that then has two components. Bra
