Conclusions

  1. 1.

    With an increase in manganese and carbon contents in austenitic Fe-C-Mn steels their mechanical properties at temperatures of 293 to 4°K increase and the magnetic permeability decreases.

  2. 2.

    Alloying of Fe-C-Mn steels with chromium leads to a significant reduction in their magnetic permeability, but sharp embrittlement at cryogenic temperatures occurs.

  3. 3.

    Aluminum has a favorable influence on the mechanical properties of Fe-C-Mn steels but leads to an increase in their magnetic permeability.

  4. 4.

    The combined addition to the steels of chromium and aluminum makes it possible to obtain in them a satisfactory combination of mechanical and magnetic properties which makes the Fe-C-Mn-Cr-Al system promising in the development of low-magnetism materials for cryogenic purposes.
