Nov 18, 2013 · 7. Phase Mixtures Observed in Fe-C Diagram • 1. Pearlite The pearlite consists of alternate layers of ferrite and cementite. It has properties somewhere between ferrite and cementite. The average carbon content in pearlite is 0.76% • 2. Ledeburite Ledeburite is an eutetcic mixture of austenite and cementite in the form of alternate layers • The Fe-C phase diagram is a fairly complex one, but we will only consider the steel and cast iron part of the diagram, up to 6.67% Carbon.

The Fe-Fe3C equilibrium lines stand at lower temperatu- res with respect to Fe-C lines, indicating the metastability of the phase diagram containing cementite. Nov 25, 2016 The iron-carbon diagram is a schema to show the connection between steel and it's Iron (Fe) and carbon (C) form a cubic space lattice or 3D lattice. Iron and carbon form a chemical compound called cementite (Fe3C). % C alloy annealed during 950 h at 725 ◦C in the + Fe3C two-phase region of the Fe–C phase diagram. The spectrum contains only two phases, namely, ferrite
