It is a generalized term. It consists of metal`s heating at a particular temperature & then cooling it down at that particular rate that produces refined microstructure. Cooling rate is normally slow. This technique is often used for softening of metals for cold-working, for improving machinability and for enhancing properties like that of electrical conductivity.

Iron is naturally occurring and a second most abundant element on earth. It is comprised of up to 80 % earth’s core and up to 30 % of earth’s crust. It cannot be found on earth in its native form under normal conditions. It is normally found in sulfide and oxide with lot of impurities. […]

Blacksmiths work with high heat so that they can create different items as per the requirement. Heating up of metals makes them malleable. It means that the metal is considerably softer and can be shaped into anything. When heated to a high enough temperature, metals like iron and steel can be bent and hammered into […]
