Using heat, radiation, pressure, chemical reactions, and many other methods to alter or improve the properties of a material by changing its composition or structure.
Some examples of materials processing include
In a sense, anything that alters the structure of a material and thus affects its properties can be considered a processing technique. Many forming methods, ways of manipulating a material into a desired shape, can also be considered processing techniques because they clearly affect the structure and property of the material.
Some of them include
