Special features of the effect of magnetic fields on the γ → α transformation in steels and alloys at low temperatures

The effect of magnetic fields on martensitic transformation in austenitic steels and alloys at low temperatures is studied. Under specific conditions magnetic fields can initiate the appearance of martensite in austenitic alloys or increase its content in steels with austenitic-martensitic structure. This causes changes in the physical and mechanical properties of the material and this should be allowed for when the metal is used in devices operating at cryogenic temperatures in the presence of strong magnetic fields.
