This paper investigates the effect of Fe, Cr and B additions, in small proportions, as
alloying elements in Ni3Al with the purpose to reduce its intrinsic fragility and extrinsic
embrittlement and to enhance, in the same time, its mechanical properties. It represents a
development of some previous research works of the authors, proving that Ni3Al-Fe-Cr-B alloys
obtained by reactive synthesis (SHS) starting from Mechanically Alloyed powder mixtures have
superior both room temperature tensile strength and ductility, and compression ones at temperatures
up to 800 °C, than pure Ni3Al. These create premises for their using as superalloys substitutes.
