Conclusions
-
1.
Ternary Fe-Mn-C alloys containing 12–45% Mn and 1.2–2.5% C exhibit structural superplasticity after deformation in tension at 770–950°C at strain rates of (0.2–2)·10−3 sec−1 both in air and in vacuum.
-
2.
Plastic deformation of samples with an original uneven structure is accompanied by refining and homogenization of the structure due to recrystallization of the alloy and diffusion of carbon, but the plasticity is far lower in this case.
