Well, basically, pearlite is the eutectic composition of steel, with an overall composition of 0.8% carbon. It is known to consist of two phases, namely: Ferrite (Fe), the room temperature of iron and Cementite(Fe3C). Therefore, the difference between pearlite and cementite is that pearlite is a composition of steel, and cementite is a composition of Pearlite. So cementite is part of pearlite.

Why ledeburite hardness more than per-lite hardness plus cementite hardness although ledeburite is per-lite plus cementite?
probably because of different thermal expansion of carbide matrix phase with pearlite or austenite disperses, at cooling a high dislocation density apears in phases, especially deformable one, and this high dislocation density is responsible for higher hardness
What are examples of heterogeneous alloys?
pearlite
What is cementite?
Cementite is a compound that is made of iron and carbon, and is sometimes referred to as iron carbide. Because it is a hard compound, it is often used to mix with steel and harden the steel.

what is the difference between Pearlite and Ledeburite?
Pearlite is a microstructure formed in steel with a specific carbon content, characterized by alternating layers of ferrite and cementite, while ledeburite is a less common microstructure formed at extremely high carbon levels, primarily composed of cementite and austenite, and is brittle in nature.
What is pearlite?
Pearlite is a layered steel product made from ferrite (iron) and cementite (iron carbide). Pearlite is stronger and lighter than regular steel, but is more prone to cracking.
What is the difference between pearlite and ferrite?
major
Difference between coarse pearlite and fine pearlite?
coarse pearlite structure has better ductility and toughness compared to fine pearlite structure but fine pearlite structure has better strength compared to coarse pearlite structure.
What is pearlie?
Pearlite is iron alloy made of ferrite(88%) and cementite(12%) formed under speciallized conditions.
What is the eutectoid point of plain carbon steel?
Eutectiod steel is 0.83% carbon within steel, Eutectiod steel is where the microstructure is completly pearlite. and no ferrite or cementite.
What are the limitation of iron iron-carbide diagram?
1) The nonequilibrium martensite does not appear on the diagram; and 2) The diagram provides no indication as to the time-temperature relationships for the formation of pearlite, bainite, and spheroidite, all of which are composed of the equilibrium ferrite and cementite phases.

What is austenite-cementite?
ledeburite
What is the difference between eutectic and eutectoid?
Eutectic point is where a liquid eutectic composition cools sufficiently to solidify.Eutectoid point is where, within a solid, the material cools enough to undergo a phase transformation. e.g. austenite to cementite a
Is pearlite a phase or a microstructure?
No
Does Pearlite absorb moisture?
yes
