Behaviour of ODS 12Cr steel under thermal treatment at micro and macro level: A positron annihilation and Vickers hardness study

The behaviour of ODS 12Cr steel under thermal treatment is studied in this report at micro and macro level. ODS 12Cr steel is always in the ferrite phase and has a melting point at 1500 ºC. Before studying,<br/>the retrieved samples were metallographically prepared in four steps: mounting, grinding, mechanically polishing and electrolytically...
