The effect of cold working followed by annealing on the development of ultrafine grained microstructure and mechanical properties of an Fe-12%Mn-0.6%C-1.5%Al medium-manganese steel was studied. The steel was cold rolled with intermediate annealings and then annealed at 873 K or 923 K for 30 min. The yield strength and total elongation of the Fe-12Mn-0.6C-1.5Al steel after cold rolling were 1200 MPa and 14%, respectively. The heat treatments resulted in the formation of two phase (austenite-ferrite) ultrafine grained microstructures with average grain sizes of 0.9 to 1.2 μm, depending on the annealing temperature. The annealed ultrafine grained steel samples exhibit the yield strength in the range of 800-950 MPa, the ultimate tensile strength in the range of 1150-1200 MPa, and total elongation of 12% to 19%.

Microstructure And Mechanical Property

In the paper, we selected high manganese steel as the binder and titanium carbide as the hard phase, which could attain single austenite bonded titanium carbide after water toughening in order to combine excellent toughness of matrix with good wear resistance of TiC organically for some components that required excellent toughness and wearability. By dint of SEM, XRD etc. detection means, effects of ingredient proportion, preparation technics and heat treatment parameters on hardness, microstructure, and mechanical property were investigated; so the composition and preparation process of TiC cemented were confirmed, which was applied to grinding with large impact force.
