Characterization of Steel
Effect of alloying elements in steel is explained along with their effect on Phase diagram and TTT diagram. Their chracterisitcs are also summarized here.
TTT diagram of steel is used for studying non-equilibirum tranformation in steel. Guide is given to study TTT diagram and its application in Material science.
Quenching of steel results in martensite. Amount of martensitic formation depends upon how fastly quenching media like water, brine and air extracts heat.
Widmanstatten structure in steel lowers hardness but they have some applications too. Find out microstructural development and ways to eliminate it.
Martensitic transformation happens when carbon steel, after heating above A1 line, cools drastically with cooling rate higher than critical cooling rate.
