Pure tungsten and tungsten alloys with minor alloying additions are known to be brittle at
room temperature and have high ductile-to-brittle transition temperatures (DBTT). Improving …

The current magnetic confinement nuclear fusion power reactor concepts going beyond
ITER are based on assumptions about the availability of materials with extreme mechanical …

Single-phase body-centered cubic (bcc) refractory medium-or high-entropy alloys can retain
compressive strength at elevated temperatures but suffer from extremely low tensile ductility …

Combinations of high strength and ductility are hard to attain in metals. Exceptions include
materials exhibiting twinning-induced plasticity. To understand how the strength-ductility …

Plasma-facing materials and components in a fusion reactor are the interface between the
plasma and the material part. The operational conditions in this environment are probably …

Body-centered cubic refractory metallic materials exhibit excellent high-temperature
strength, but often suffer from brittle intergranular fracture due to the recrystallization-induced …

Dislocation cores, the regions in the immediate vicinity of dislocation lines, control a number
of properties such as dislocation mobility, cross-slip and short-range interactions with other …

We have developed empirical interatomic potentials for studying radiation defects and
dislocations in tungsten. The potentials use the embedded atom method formalism and are …

Slip in face centred cubic (fcc) metals is well documented to occur on {111} planes in< 110>
directions. In body centred cubic (bcc) metals, the slip direction is also well established to …

Tungsten materials are candidates for plasma-facing components for the International
Thermonuclear Experimental Reactor and the DEMOnstration power plant because of their …
