| 4. | Description | Abstract | Relaxation resistance and corrosion resistance of samples of ultrafine-grained steel 08H18N10T obtained by the method of equal-channel angular pressing at temperatures of 150 and 450 °C are investigated. For ultrafine-grained steel with high values of the limit of macroelasticity and yield strength, a decrease in the Hall—Petch coefficient due to fragmentation of δ-ferrite particles at the method of equal-channel angular pressing is shown. It is established that the samples of ultrafine-grained steel have 2-3 times higher relaxation resistance compared to coarse-grained steel. It is noted that the method of equal-channel angular pressing leads to an increase in the rate of general corrosion. At the same time, despite the decrease in corrosion resistance, samples of ultrafine-grained steels have high resistance to intercrystalline corrosion. It is established that the decrease in corrosion resistance of ultrafine-grained steel is due to an increase in the volume fraction of martensite deformation at the method of equal-channel angular pressing. |
