Fracture behavior of 9% and 14% Cr ODS steels prepared by mechanical alloying

Popis výsledku v původním jazyce

The paper describes the influence of the microstructure (coming from the chemical composition and extrusion shape) of 9 and 14%Cr-W(Mo)-Ti-Y2O3 ODS steels prepared by mechanical alloying and subsequent hot-extrusion on their impact properties. 9Cr-2W ferritic-martensitic steel present lower upper shelf energy (USE) about 7 J and a lower ductile to brittle transition temperature (TDBTT) about -30°C compared to 14Cr-1W ferritic steel one. The transition energy curves of low-activation ferritic 14Cr-1W ODSsteel was shifted by about 50°C toward lower temperatures and USE by about 4 J towards higher energies. The extrusion shape also plays a role on the impact properties. The texture caused by the forming process strongly influenced the impact behavior ofthe steels. The extensive splitting of the fracture surfaces of plate shaped steel comparing with steels extruded as bar was found.
