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...

Deformation of Metals

Deformation is the change in dimension or forms of matter under the action of the applied forces. Deformation is caused either by the mechanical action of the external forces or by various physical and physio-chemical processes. Deformation may be permanent or temporary depending upon the...

Property Changes by Deformation

Due to the cold working of metals, there arise a large number of dislocation and distortions of planes. Cold working of metals or alloys increases the hardness, yield strength, ultimate strength and electrical resistance whereas the ductility and plasticity are decreased. Following are some important...

Effect of Alloying Metals

An alloy is a substance having metallic properties. Alloying is done by combining one metallic element with one or more metallic or non-metallic elements. In an alloy, the metallic or non-metallic elements do not exist or operate in distinct layers when solid. An alloy when...

Aluminium and its Alloys

The non-ferrous metals are those which contain a metal other than iron as their chief constituent. The non-ferrous metals are usually employed in industry due to the following characteristics: Easy to fabricate i.e., casting, rolling, forging, welding and machining, High resistance to corrosion, Very good...

Titanium & Zirconium Alloys

Titanium is a chemical element with the symbol Ti and atomic number 22. Sometimes called the “space age metal”, it has a low density and is a strong, lustrous, corrosion-resistant (including sea water and chlorine) with a silver color. Titanium can be alloyed with Iron,...
