What is the name of the two-phase microstructure found in steels resulting from the eutectoid transformation of austenite and consisting in alternate layers of ferrite and cementite
Here I hope this is what you need?
When austenite in iron-carbon alloys is transformed isothermally below the eutectoid temperature at small undercooling, it undergoes eutectoid transformation to produce a unique micro- structure termed “pearlite”, which was discovered by Sorby in 1864.
