Creep of Cr2O3 and yttrium doped Cr2O3

AbstractCompressive creep tests of pure and Y doped Cr2O3 from 1217 to 1417°C have shown that the presence of Y substantially increases diffusional flow rates. It is suggested that this increase in deformation rate may account, in part, for the empirical evidence that improved adherence to the underlying metal is provided by Y containing scales compared with pure scales.MST/819
