| Cumulative isochronal annealing of stainless steel 1.4307 samples deformed by compression was investigated using the Doppler broadening of the annihilation line measurements. Higher level of plastic deformation is accompanied not only by higher concentration of defects but also by higher amount of α' martensite. The annealing studies revealed creation of defects in the temperature range between 450°C and 650°C pointing out the reverse transition of α' martensite to austenite. This is confirmed by magnetic susceptibility and microhardness measurements. |
