FOR the sake of simplicity, we shall consider the case of an eutectoid steel ; if the steel is cooled slowly from the austenitic region, a well-known pearlite structure is formed in crossing the ...

The hypoeutectoid steel is the most ductile and the ductility has decreased by a factor of three for the eutectoid alloy. In hyper-eutectoid alloys the additional, brittle cementite on the pearlite ...

Spheroidizing of high carbon steel is a method of prolonged heating at a temperature below the eutectoid temperature. By heating at this temperature pearlite, which is the lowest energy arrangement of ...

The microstructure is now a ploycrystalline pearlite with the hard-brittle proeutectoid cementite on the grain boundaries. This structure makes the alloy more brittle than the eutectoid pearlite ...
