As a promising alternative, this work aimed to design ferritic-martensitic 9Cr-1W steels of Eurofer type strengthened by a homogeneous dispersion of nitrides. AlN and BN were selected for this pioneering study, and the two nitride dispersion strengthened (NDS) steels were prepared by mechanical alloying and compacting using spark plasma sintering (SPS). Their mechanical properties were assessed by tensile tests ranging from room temperature to 800 degrees C and compared to the tensile characteristics of conventional as well as oxide dispersion strengthened (ODS) 9Cr-1W steels. The strength of the two NDS steels presented here was comparable or even higher than that of the conventional and the ODS variants. Furthermore, the uniform plastic strain behaviour of the NDS steels was similar to the ODS counterparts prepared by HIP or SPS from mechanically alloyed powders. In addition, the BN reinforcement effectively prevented large plastic deformation at temperatures above 600 degrees C that would typically result in a significant increase in total elongation, a phenomenon encountered in 9Cr-1W steels. This quality could open a new application window and potentially lead to the development of heat-resistant low-chromium 9Cr-1W type steels.
