From: Core-multishell globular oxidation in a new TiAlNbCr alloy at high temperatures
A typical core-multishell globular oxide of TiAlNbCr alloy after oxidation at 900 °C for 100 h. (a) and (b) Morphologies of oxides with a globular structure, which consist of a core Y2O3 particle and multi-layered TiO2/Al2O3-rich/TiO2-rich shells from the inside to outside, and (c) elemental distributions via EPMA mapping for the globular oxide, where the detailed chemical microanalysis results are shown in Table 2.
