Abstract
A eutectoid polyhedration of the phase diagram of the Fe-C-Mn system is presented, which shows that the structure of manganese steels can contain eutectoids of two kinds that can be in a state of peritectoid equilibrium with austenite. A conode polyhedration of the diagram is performed as applied to the composition of steel 2G. The structural features ensuring precipitation hardening or composite hardening of steels 20G and 110G13L are considered.
