CLASSIFICATION OF MATERIALS BASED ON ENERGY BAND THEORY . Workshop classification and labelling of metals | 08 February 2012 13 Mixtures As the affinity of metals to AVS differs, it is possible that above a certain loading metals will compete for the (limited) AVS available. This report highlights the classification of the engineering materials and their processing techniques.

The metal is subjected to stress.It is a process of changing the shape and size of the material under the influence of external force or stress.Plastic Deformation occurs. Classification of Metals •Ferrous-those based on iron Steels Cast irons •Nonferrous-all other metals Aluminum, magnesium, copper, nickel, titanium, zinc, lead, tin, molybdenum, tungsten, gold, silver, platinum, and others •Superalloys These elements were classified by Lavoisier in to metals and non-metals by studying their properties. Casting made from any metal that can be melt and can have any configuration the designer desires. 1.
