The effect of boron content(0 to 2.22 at.-% )on isothermal oxidation behaviour of Ni_3Al at 750 to 1150℃ for 3 to 100 h has been studied.The results show that the isothermal oxidation kinetics of Ni_3Al with various B contents at different temperatures obeys the parabolic law. The compounds with 0.52 to 1.37 at.-%B show the best oxidation resistance.The morphology and microstructure of the scales have also been investigated.
