Abstract Effect of Al, Cr, Fe and Mo concentrate on the resistance of cavitation erosion of Ni3Al based alloys was studies, the results show that Zr and B toughened Ni3Al alloy with Al concentrate of 6%-9% possesses excellent resistance of cavitation erosion and the decrease of the γ' forming elements concentrate causes the decline of the resistance of cavitation erosion. The introduction of Fe and Mo somewhat decreases the resistance to cavitation erosion.
