Summary
The authors have investigated the influence of the type of oxide on the structural stability of dispersion-hardened nickel over the temperature range 1000–1350°C. Alloys of nickel strengthened with aluminum, silicon, zirconium, and hafnium oxides were studied. It was established that such factors as the density, melting point, energy of formation, etc., of oxides affect their stability. The capacity for growth of the oxides investigated increases in the series: HfO2<ZrO2<α-Al2O3<SiO2<γ-Al2O3.
