The steel have only 0.8% carbon contain called eutectoid steel & the steel has 0 to 0.8% carbon contain called hypo eutectoid steel & steel have contained 0.8 to 2.1% carbon called hyper-eutectic steel.

By lever rule, we can get the solid and liquid composition in a compound in iron carbon diagram.

Is it possible to get 100% pearlite at hypo or hyper eutectoid steel? Give Reason.

The mixture of pearlite and cementite is what?

@Kanugula Rav.

Lever rule means?

The Steels which contains 0.77% carbon are known as Eutectoid Steels. It consists of wholly Pearlite. The steels which contains less than 0.77% carbon are known as hypo eutectoid steels. It consists of pearlite and proeutectoid ferrite. The steels which contains greater than 0.77% carbon are known as hyper eutectoid steels. It consists of pearlite and proeutectoid cementite.

Steel which contain 0.8% of carbon its known as eutectoid steel, pearlite contain cementite and ferrite. So it was wholly pearlite.

Eutectiod steel contains 100% of pearlite, which is consisting of 0.8% of carbon and in which that 100% pearlite contains 88% ferrite and and 12% cementite according to lever rule.

Pearlite = Cementite+Ferrite.

The eutectoid composition of ferrite and cementite is referred to as pearlite.
