  1. Mode 1—no treatment; mode 2—holding for 4 h in water vapor in Ar–5 vol% H2 mixture atmosphere at 600 °C under the pressure of 0.15 MPa (water vapor pressure 0.03 MPa); and mode 3—holding for 4 h in water vapor in Ar–5 vol% H2 mixture atmosphere at 600 °C under the pressure of 0.15 MPa (water vapor pressure 0.148 MPa). A as-received material, R one-time reduction in Ar–5 vol% H2 mixture for 4 h at 600 °C under the pressure of 0.15 MPa. RO redox treatment for 5 cycles (reduction in Ar–5 vol% H2 mixture–oxidation in air)
