What is Metallography
What is Metallography? The study of internal structure of a metal or alloy, in relation to its physical and mechanical properties, under a microscope is called metallography. When the structure…
What is free cutting steel
A steel with a higher than usual content of sulfur and phosphorus intended for the fabrication of parts for high-speed automatic and semiautomatic machine tools. Free-cutting steel is produced in…
Stainless Steel | Engineering Materials
Stainless Steel is defined as that steel which when correctly heat treated and finished, resists oxidation and corrosive attack from most-corrosive media. The different types of stainless steels are as…
Allotropic Forms of Pure Iron
Allotropic Forms of Pure Iron - we know that pure substances may exist in more than one crystalline form. Each such crystalline form is stable over more or less well…
Metals for Nuclear Energy
The various metals for producing nuclear energy are used as raw materials for moderators, reflectors, fuel elements, fuel canning materials, control elements and pressure vessel materials. The important metals used…
High Temperature Alloys
What are high temperature alloys? The high temperature alloys are those alloys which can withstand temperature in excess of 1100 degree celcius. These alloys are used in components of nuclear plants,…
Cast iron and its types
The cast iron is obtained by remelting pig iron with coke and lime stone in a furnace known as cupola. It is primarily an alloy of iron and carbon. The carbon contents…
Engineering Materials
It is a science that deals with the association among the structure and the properties of the materials. Properties of materials: Properties of the materials are divided in to six…
Effect of grain size on mechanical properties of metals
What is the effect of grain size on mechanical properties of metals? All solid metals are crystalline and the crystals or grains are made up of several atoms. The grain…
Alloy Steel | Engineering Materials
An alloy steel may be defined as a steel to which elements other than carbon are added in sufficient amount to produce an improvement in properties. The chief alloying elements…
