Mechanical performance and oxidation resistance of an ODS ?-TiAl alloy processed by spark plasma sintering and laser additive manufacturing

In this work, the influence of Y2O3 additions on the mechanical properties and oxidation resistance of a Ti-45Al-3Nb (at.%) alloy have been studied. In particular, the mechanical properties from 293 K to 1073 K and oxidation resistance at 1073 K of spark plasma sintered and direct metal deposited ma...
