Influence of microstructure on impact properties of 9?18%Cr ODS steels for fusion/fission applications

Original language description

The paper describes the influence of the microstructure of (9?18%)Cr?W?Ti?Y2O3 ODS steels on their impact fracture properties. The extrusion shape plays a major role on the impact properties, materials extruded as a rod present a higher upper shelf energy (USE) and a lower ductile to brittle transition temperature (DBTT) compared to materials extruded as plates. The DBTT for the non-recrystallized 14%Cr ferritic steels was shifted towards higher temperatures compared to the 9%Cr tempered ferritic?martensitic steel. Increasing the W and Ti content in 9%Cr tempered ferritic?martensitic ODS steel leads to a USE and a DBTT shifted towards higher energies and higher temperatures, respectively. Increasing the yttria content leads to a drop of the impact energy and a shift of the DBTT of ferritic ODS steel towards higher temperatures. The present study highlights extensive splitting of the fracture surfaces and a dependency of the impact energy on the fracture plane orientation according to t
