Solid-state oxidation kinetics of an yttrium-containing AK1M2 alloy

详细

The interaction of an yttrium-modified AK1M2 alloy with atmospheric oxygen in the temperature range 723–823 K is studied by thermogravimetry. The kinetic parameters of oxidation are determined. An yttrium addition is shown to decrease the oxidation rate, which is accompanied by an increase in the apparent oxidation activation energy from 114.9 to 134.6 kJ/mol.
