Question

difference between pearlite and cementite

Answer 1

Pearlite is a two-phased, lamellar (or layered) structure composed of alternating layers of ferrite (88 wt%) and cementite (12 wt%) that occurs in some steels and cast irons. ... Likewise steels with higher carbon content (hypereutectoid steels) will form cementite before reaching the eutectoid point..

I hope it helps u dear☺️.......

PEARLITE - A finely laminated mixture of ferrite and cementite present in cast iron and steel formed by cooling of austenite .

CEMENTITE - A hard brittle iron carbide present in cast iron and most steels . Fe3N
