Microstructure examination of Fe-14Cr ODS ferritic steels produced through different processing routes

Nadine Baluc, Zbigniew Oksiuta

Various thermo-mechanical treatments were applied to refine and homogenise grain size and improve mechanical properties of hot-isostatically pressed (HIP) 14%Cr ODS ferritic steel. The grain size was reduced, improving mechanical properties, tensile streng ...

Effect of vanadium addition on the microstructure and mechanical properties of the ODS ferritic steels

Nadine Baluc, Zbigniew Oksiuta

In this work, the effects of vanadium addition in the range of 0.3-3% (in weight percent) for an oxide dispersion strengthened reduced activation ferritic (ODS RAF) steel were investigated. Samples of the V-modified steel have been prepared using elemental ...

Influence of hot rolling and high speed hydrostatic extrusion on the microstructure and mechanical properties of an ODS RAF steel

Nadine Baluc, Zbigniew Oksiuta

An argon gas atomized, pre-alloyed Fe-14Cr-2W-0.3Ti (wt.%) reduced activation ferritic (RAF) steel powder was mechanically alloyed with 0.3wt.% Y2O3 nano-particles in an attritor ball mill and consolidated by hot isostatic pressing at 1150 °C under a press ...

Optimization of the chemical composition and manufacturing route for ODS RAF steels for fusion reactor application

Nadine Baluc, Zbigniew Oksiuta

As the upper temperature for use of reduced activation ferritic/martensitic steels is presently limited by a drop in mechanical strength at about 550 degrees C, Europe, Japan and the US are actively researching steels with high strength at higher operating ...
