Abstract
The characteristics of low-cycle fatigue of high-chromium martensitic steel 10Kh10K3V2MFBR are determined at room temperature and specified deformation amplitude varied within 0.25 – 1.0%. It is shown that the steel is susceptible to softening under low-cycle loads. The endurance of the steel is determined by the Baskvin – Manson – Coffin relation. Permanent softening of the steel until failure is caused by lowering of the dislocation density and coarsening of subgrains.
