X-ray diffraction study of the oxidation of Ni3(Al, Ti) alloys

  • Published:
Soviet Powder Metallurgy and Metal Ceramics Aims and scope

Conclusions

A study was made of the phase composition of the scale forming on Ni3(Al + 15 at.% Ti) and Ni3(Al + 5 at.%Ti) alloys during atmospheric oxidation at temperatures ranging from 600 to 1000°C. The scale was found to contain the oxides NiO, TiO2 (rutile),γ-Al2O3, NiO · TiO2, NiO · Al2O3, Ti3O5, and Ti2O3 together with Ni and a nickel base solid solution (Niss). The character of the distribution of these phase constituents in successive scale layers after oxidation under various conditions is described. A correlation was found between the phase composition of the scale and certain kinetic oxidation characteristics of the alloys.
