Introduction to Metallurgy

The single most used material today in the Industry is Metal. The reason for the increased use of the metals is due to its wide range of properties: Lustre Hardness Low specific heat Plastic deformability Good thermal conductivity Relatively high melting point Strength Ductility Malleability...

Structure of Materials

It should be clear that all matter is made of atoms. From the periodic table, it can be seen that there are only about 100 different kinds of atoms in the entire Universe. These same 100 atoms form thousands of different substances ranging from the...

Structure of Atom

An atom consists of Protons, Neutrons and Electrons. The Protons (+ve charged particles) and Neutrons form the nucleus of the atom around which the Electrons (- ve charged particles) rotate. The number of protons in the nucleus is referred as its Atomic number. The Mass...

Crystal Structures for Metallic Elements

The crystals of most metals have highly symmetrical structure. The most common types of lattices are (a) Body Centred Cubic Structure (BCC) (b) Face Centred Cubic Structure (FCC) (c) Hexagonal Close Packed Structure (HCP) Body Centred Cubic Structure (BCC) – In this type of structure, atoms...

Atomic Arrangement in Metals

A metal can exist in the gaseous, liquid or solid states depending upon the pressure and temperature. Metals have the ability to donate electrons and form a positive ion. Metals have high density, high melting temperature, good electrical and thermal conductivity, metallic lustre and crystalline...
