Abstract: Cast Fe + (12.7 – 25.6) % Mn + (0 – 14.4) % Al + (0.02 – 2.18) % C alloys including microalloyed by nitrogen (0,001 – 0,135) % N with high specifi c strength are experimentally investigated and studied. It is shown that cast high-carbon Fe – Mn – Al – С alloys, well give in to a hot deformation, up to 40 – 50 % of reduction without a fi recracking. At a warm strain in investigated alloys the high-tensile condition (σв to 1810 MPa) is realised at a toughness adequate supply (to 50 %). The Yield stress of high-carbon austenitic alloys (to 2.18 %) Fe – Mn – Al – С at room temperature attains 1200 MPa. Thermal capacity and thermal conduction decrease with increase at total alloying Al + C + N. Investigated alloys of iron with high contents of Mn and Al have high specific strength and can be used in cast and strain con-dition as high-strength with a toughness large supply, heatproof and wear-resistant.
