Effect of second-phase particles on the oxidation behaviour of a high-manganese austenitic heat-resistant steel

Effect of Mn addition on microstructure and mechanical properties of GX40CrNiSi25-12 austenitic heat resistant steel

“…They found that the matrix maintained the austenitic structure when adding 3.2wt.% to 12.8wt.% Mn to the steel, and the overall mechanical properties of the steel were optimal at a Mn content of 8wt.%. Liu et al [18][19] investigated the oxidation behavior of a high-manganese austenitic heat resistant steel, and they pointed out that the introduction of second phase particles helped to improve the oxidation resistance and oxide spalling resistance. Lee et al [20] studied the effect of Nb and Cu addition on the creep properties of a high Mn-N austenitic heat resistant steel and discussed the thermodynamics and kinetics of the precipitation by using thermo-kinetic simulations.…”
