A systematic study of the effects of Ti, Ta and Nb on the hot corrosion behavior of alloy system Ni-16Cr-gAl-2W-1Mo-4Co-(0~4)Ti-(0~4)Ta-(0~4)Nb (at%) was conducted. The results showed that, in certain compositional regions, the hot corrosion resistance in 75% Na2SO4+25%NaCl molten salt of the expermental alloys was similar to that of IN738LC alloy. The hot corrosion property balances with other properties, which provides the basis for selecting alloy compositions to develop single crystal superalloys of high performance hot corrosion resistance.
