| Abstract Scope |
Tungsten is considered as the material of choice for the divertor application of fusion power plants due to its intrinsic thermo-physical properties. One main drawback is the recrystallization induced reduction of its mechanical properties at elevated temperatures. The aim of this research was to improve the material properties to be able to sustain plasma-facing conditions, especially to be able to resist high thermal loads imposed on the divertor during operation. The reinforcement of tungsten by incorporation of carbide nanoparticles, resulted in a material with a stable microstructure and promising behaviour. WC nanoparticles were used as a source for the in-situ formation of W2C inclusions in the W matrix during the thermal treatment of powder mixtures with a field assisted sintering technique.
This work has been carried out within the framework of the EUROfusion Consortium No633053. The projects ARRS: P2-0087-2, P2-0405-5 and J2-8165 and MAT2015-70780-C4-4-P and S2013/MIT-2862-MULTIMATCHALLENGE are acknowledged. |
