Effect of Mn, Al, Ni, and C Content on the Equilibrium Phase Composition of Alloys Based on the Fe–Mn–Al–Ni–C System

Metallurgist Aims and scope

A Thermo-Calc program is used to calculate isothermal and polythermal sections of diagrams and phase composition for alloys of the Fe–Mn–Al, Fe–Mn–Al–Ni, and Fe–Mn–Al–Ni–C systems. Phase diagrams are used to study the effect of nickel, aluminum, manganese, and carbon on the equilibrium structure of alloys of the Fe–Mn–Al–Ni–C system. Concentration ranges are determined for existence of single-phase γ-alloys in the range 1000–1200°C. It is established that achievement of a considerable aluminum content (10%) and existence of increased specific strength for austenitic alloys of the Fe–Mn–Al–Ni–C system containing not less than 5% Ni is possible with a manganese content of not less than 20% and carbon not less than 1.4%.
