abstract = {High ductile-to-brittle transition temperature,
recrystallization-induced embrittlement, and
neutron-irradiation-induced embrittlement are potential
drawbacks related to the mechanical properties of tungsten
(W) for plasma facing materials of fusion reactor divertors.
To improve the mechanical properties, resistance to
recrystallization and neutron irradiation, W materials
modified by potassium doping and alloying by rhenium have
been developed. In this paper, thermal shock behaviors of
these W materials under high heat flux tests were
investigated, which simulated an edge localized mode of
plasma occurring in fusion reactors as a transient event.
The thermal shock tests were performed with an electron beam
facility, JUDITH 1, and post-mortem analyses to evaluate the
damage caused by the thermal shock tests were carried out.},
