Formation of the Z-phase and prospects of martensitic steels with 11% Cr for operation above 590°c

  • Published:
Metal Science and Heat Treatment Aims and scope

Prospects of commercial use of new-generation martensitic thermomechanical steels created on the basis of Fe – 11% Cr steels are considered. The physical causes of degradation of mechanical properties in the process of creep of these steels at ≥ 590°C are studied in detail. It is shown that the degradation is connected with formation of the Z-phase. The mechanisms of formation of the phase are described.
