abstract = {The use of self-passivating tungsten alloys for the first
wall armor of future fusion reactors is advantageous
concerning safety issues in comparison with pure tungsten.
Bulk W-10Cr-0.5Y alloy manufactured by mechanical alloying
followed by HIP resulted in a fully dense material with
grain size around 100 nm and a dispersion of Y-rich oxide
nanoparticles located at the grain boundaries. An
improvement in flexural strength and fracture toughness was
observed with respect to previous works. Oxidation tests
under isothermal and accident-like conditions revealed a
very promising oxidation behavior for the W-10Cr-0.5Y alloy.
Thermo-shock tests at JUDITH-1 to simulate ELM-like loads
resulted in a crack network at the surface with roughness
values lower than those of a pure W reference material. An
additional thermal treatment at 1550 °C improves slightly
the oxidation and significantly thermo-shock resistance of
the alloy.},
