.... Elements investigated for this purpose include Ni, Fe, Cr, Mn, Co, Zr, Gd, Hf, Y, Sc, Nb, and V. When alloyed with Al, some elements form incoherent dispersoids, such as in the Al-Fe-Ce, Al-Fe-V-Si, Al-Fe-Ce-W, and Al-Cr-Zr-Mn systems. Alloying Al with Sc forms coherent dispersoids, where their low...

... wave of research is now investigating new aspects of these aluminides. For example, for Fe-Al alloys, a eutectoid reaction from Fe5Al8 to an ultrafine (<100 nm) lamellar structure of FeAl2 and FeAl yields a microstructure that can rapidly form a passivating -Al2O3 scale upon oxidation without any...

.... Crucially, they would be scrap-compatible with each other. Their approach was to keep enough excess Si to provide the hardening response, plus eliminate Cr and reduce Fe to improve formability. They differentiated between the two alloys by adjusting the Si and Mg levels, tuning either for strength...
