1. Bulk Ti-Al alloy was subjected to 1100 K oxidation for 5 hr, which led to the growth of 3.5 micrometre thick oxide scale. Note that, at this temperature, there is high probability of formation of different titanium oxide (TiO, Ti203, TiO2) as well as aluminium oxide (Al2O3) phases. How would you characterize the entire microstructure of the oxide as well as changes to the bulk microstructure because of this oxidation? You have the option of using any/all of XRD, XRF only. Explain in detail.
