| Abstract Scope |
At temperatures the Cantor alloy is severely oxidized in air, with the formation of many different types of oxides as this can be observed after test by post-mortem metallographic characterization. It can be interesting to better know the sequences of appearance of these different oxides all along the exposure to hot air, in order to better specify the roles of each of the five elements present in a Cantor alloy. This was done in the present work with the oxidation by laboratory air, for different durations, in a resistive tubular furnace. A series of seven samples was prepared. They were subjected to oxidation fat 1000°C for seven durations ranging from 1.5 to 62 hours. The progressive oxidation states were characterized by X-ray diffraction, SEM observation of the outer side of the scales, and cross-sectional examination of the whole thickness of the scale as well as the chemical changes in subsurface. |
