英文摘要Deformation bonding is a highly promising process to make homogenized large ingots. Although performing in vacuum, the oxidation at bonding interface is inevitable. This work investigates the oxidation behavior of IN718 in vacuum. The initial oxide scale is composed of an inner layer of delta *-Al2O3 and an outer layer of anatase-type Ti(1-x)Al(x)O2 with rutile-type Ti1-xNbxO2 particles at their oxide/vacuum interfaces. With the increase of oxidized time, oxides tend to decompose and transform. The stable order is rutile-type Ti1-xNbxO2 < anatase-type Ti1-xAlxO2 < rutile-type TiO2 < delta *-Al2O3 < alpha-Al2O3. Preferential oxidation of MX, MX/matrix interface and grain boundary are also discussed.
