Metals and metallic alloys

Grain size (metals)

Crystalline structures comprised of individual grains

Alloy

A mixture that contains at least one metal. Can be a mixture of metals or metals and non-metals

Super alloys

An alloy that exhibits excellent mechanical strength, resistance to thermal creep deformation, good surface stability and resistance to corrosion

Tempering

A heat treating process designed to increase the toughness of an iron-based metal by heating it and allowing it to cool in air

Creep (deformation)

The slow, permanent deformation of a solid material under the influence of a mechanical stress

Oxidization resistance

A property of a material that means that it does not readily react with oxygen and degrade

Chemically inert

Lack of reactivity with other materials

Disposal

metals and metal alloys are easily recyclable
