Influence of 1 and 5 wt% TiC additions on the oxidation behaviour of pure tungsten. Nuclear Materials and Energy, 24, 100780.2352-1791https://hdl.handle.net/10016/36668Proceedings of: 19th International Conference on Fusion Reactor Materials (ICFRM-19), 27 October-01 November 2019, La Jolla, California, U.S.AThe influence of 1 and 5 wt% of TiC nanoparticles on the oxidation behaviour of reinforced tungsten has been evaluated up to 700 °C in dry air. Isothermal thermogravimetric tests prove that the addition of 5 wt% of TiC particles is detrimental, increasing the mass gain of pure tungsten by a factor of ten. TiC particles act as stress concentrators, facilitating microcracking events within the scale and promoting decohesion between TiC-free boundaries and TiC-containing regions of the material. Compared to pure tungsten, lowering TiC addition to 1 wt% significantly improves the oxidation resistance at 700 °C by reducing about seven times the mass gain, while at 600 °C both materials exhibit similar resistance. At 700 °C, the presence of 1 wt% of TiC particles inhibits massive microcracking events occurring in the scale formed on pure tungsten, rendering the oxide scale denser and more protective.9eng© 2020 The Authors.Atribución-NoComercial-SinDerivadas 3.0 EspañaTungstenCompositesOxidation resistanceReinforced materialsTICTitanium carbideconference outputEnergía NuclearFísicaMaterialesQuímicahttps://doi.org/10.1016/j.nme.2020.100780open access11007809Nuclear Materials and Energy.
