Steel Making and Casting How do we get the perfect ratio of chemical element to enable us to achieve the correct properties in our product? In this module introduction to metallurgy will look at the key processes to take Iron ore and produce steel.
Metallurgy for Beginners –
Introduction to iron ores, blast furnaces and ladle metallurgy, and will then have a more in depth look at Blast furnaces, Basic Oxygen Steelmaking, Electric Arc Furnaces and Casting.
Metal Forming and Processing How do we introduction to metallurgy the material from steel making and casting into a media that is high quality and useful? In this introduction to metallurgy we will have an overview of hot, warm and cold forming.
Extrusion — a hot and malleable metal is forced under pressure through a dieintroduction to metallurgy shapes it before it cools. Sintering — a powdered metal is heated in a non-oxidizing environment after being compressed into a die.

Machining — lathesmilling machinesand drills introduction to metallurgy the cold metal to shape. Fabrication — sheets of metal are cut with guillotines or gas cutters and bent and welded into structural shape.
Work hardening creates microscopic defects in the metal, which resist further changes of shape. Various forms of introduction to metallurgy exist in industry and academia.

These include sand castinginvestment casting also called the lost wax processdie castingand continuous castings.
Each of these forms has advantages for certain metals introduction to metallurgy applications considering factors like magnetism and corrosion. Common heat treatment processes include annealingprecipitation strengtheningquenchingand tempering.
Quenching is introduction to metallurgy process of cooling a high-carbon steel very quickly after heating, thus "freezing" the steel's molecules in the very hard martensite form, which makes the metal harder. There is a balance between hardness and toughness in any steel; the harder the steel, the less tough or impact-resistant it is, and the more impact-resistant it introduction to metallurgy, the less hard it is.
Tempering relieves stresses in the metal that were caused by the hardening process; tempering makes the metal less hard while making it better able to sustain impacts without breaking. Often, mechanical and thermal treatments are combined in what are known as thermo-mechanical treatments for better introduction to metallurgy and more efficient processing of materials.
These processes are common to high-alloy special steels, superalloys and titanium alloys. Ferrous metals From to the 20th century, metallurgical development was still introduction to metallurgy concerned with improved technology in the manufacture of iron and steel.
In England, the gradual exhaustion of timber led first to prohibitions on cutting of wood for charcoal and eventually to the introduction of coke, derived from coal, as a more efficient fuel. Thereafter, the iron industry expanded rapidly in Great Britainintroduction to metallurgy became the greatest iron producer in the world.
The crucible process for making steel, introduced in England inby which bar iron and added materials were placed in clay crucibles heated by coke fires, introduction to metallurgy in the first reliable steel made by a melting process.
One difficulty with the bloomery process for the production of soft bar iron was that, unless the temperature was kept low and the output therefore smallit was difficult to keep the carbon content low enough so that the metal remained ductile.
This introduction to metallurgy was overcome by melting high-carbon pig iron from the blast furnace in introduction to metallurgy puddling processinvented in Great Britain in In it, melting was accomplished by drawing hot gases over a charge of pig iron and iron ore held on the furnace hearth.
