Brittleness of austenitic steels alloyed with manganese

  • 32 Accesses

Conclusions

  1. 1.

    During plastic deformation secondary phases (α- and ε-martensitic phases) are formed; they are precipitated in the grain boundaries, which embrittles the alloy. Manganese α-martensite, unlike the α-martensite of chromium-nickel austenitic steels, has a high brittleness. For low-carbon (unstable) manganese austenite MS lies in the range of 10–150°C [16], resulting in plentiful formation of martensite and, consequently, an increase of brittleness at low temperatures.

  2. 2.

    The method of radioactive decoration showed that carbon and phosphorus are concentrated in the grain boundaries and increase the susceptibility of manganese austenite to cold brittleness.

  3. 3.

    The carbide phases formed with suitable alloying or heat treatment are of particular importance. The precipitation of carbides in the grain boundaries causes a sharp reduction of the impact toughness.
