Eutectiod steel is 0.83% carbon within steel, Eutectiod steel is where the microstructure is completly pearlite. and no ferrite or cementite.
as the specification indicates there is 0.85% carbon in 1085 carbon steel and 0.95% carbon in 1095 carbon steel. according to the iron-iron carbide equilibrium diagram the hardness of the steel is mainly attributed to the cementite formation. and the cementite content increases as the percentage carbon increases hence 1095 is harder than the 1085 grade steel.

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.
ledeburite
Martensite
It's 6.67%.
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.
The are three types of cementite which form in different ways. There's the primary that forms from crystalization from the molten iron above 4.3%C and below 6.7%C (line CD in Fe-Fe3C diagram), secondary cementite which forms from precipitation from austenite at the right side of the eutectoid point. And there's the tertiary cementite which forms as precipitation from ferrite alpha because of the falling solubility of carbon in ferrite as temperature goes down.
A bainite is a microstrucutre of steel consisting of needle-like particles of cementite embedded in a ferrite matrix.
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.
Pearlite is iron alloy made of ferrite(88%) and cementite(12%) formed under speciallized conditions.
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
Eutectiod steel is 0.83% carbon within steel, Eutectiod steel is where the microstructure is completly pearlite. and no ferrite or cementite.
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.
