Investigation of the structural-phase state and its role in the formation of heat-resistance properties of 12% chromium steel

Results of investigations into the structural-phase state of ÉK-181 ferritic-martensitic low-activate steel after thermal treatment including quenching, intermediate tempering, and subsequent long tempering under loading at temperatures of 923 and 973 K are presented. The influence of the defect sub...

Description
Summary:Results of investigations into the structural-phase state of ÉK-181 ferritic-martensitic low-activate steel after thermal treatment including quenching, intermediate tempering, and subsequent long tempering under loading at temperatures of 923 and 973 K are presented. The influence of the defect substructure of the ferrite matrix, phase composition, and character of the secondary dispersed phase distribution in the volume of the material on the heat-resistant steel properties is examined.
