MME 214 Metallography sessional Exp. 2 Microstructure of Wrought Iron Wrought Iron • Wrought iron was once the most important metallic engineering material but it has now been almost totally replaced by the different grades of steel. • A little wrought iron is still made and will probably continue to be made since it possesses certain extremely valuable properties. • Wrought iron is a soft but ductile metal made from pig iron by a low temperature oxidation process called ‘Puddling’. • It is

------------------------------------------------- Alloy Steel is a metal alloy whose major component is iron‚ with carbon content between 0.02% and 2.14% by mass. An alloy is a metallic solid solution composed of two or more elements. Complete solid solution alloys give single solid phase microstructure‚ while partial solutions give two or more phases that may or may not be homogeneous in distribution‚ depending on thermal (heat treatment) history. Alloys usually have different properties from those

Mayceemae M. Barnuevo CHEM 17.1 13L Group 1 February 7‚ 2014 February 19‚ 2014 Exercise 12 SOME INVESTIGATIONS ON THE CORROSION OF IRON I. Introduction Metals undergo natural destruction that allows a spontaneous deteriorating reaction where they return to their original state from where they are obtained upon contact with the surrounding‚ particularly when reacted to oxygen. Such phenomenon is known as corrosion (Zumdahl‚ 1998). This leads the surface of the materials to rust in due time. Usually

Iron Making Technology A thousand years before the age of empires in Rome and Greece‚ the Iron Age was ushered into the world with the clank and clatter of the blacksmith’s anvil. The transition from the Bronze Age occurred at different times in different spots on the globe‚ but when and where it did‚ the distinctive dark metal brought with it significant changes to daily life in ancient society‚ from the way people grew crops to the way they fought wars. Iron has remained an essential element

a type of corrosion but the term is restricted to iron or products made from it. Iron is easily prone to rusting making its surface rough. Chemically‚ rust is a hydrated ferric oxide. Rusting‚ an electrochemical mechanism: Rusting may be explained by an electrochemical mechanism. In the presence of moist air containing dissolved oxygen or carbon dioxide‚ the commercial iron behaves as if composed of small electrical cells. At anode of cell‚ iron passes into solution as
