Size effects on the tensile properties and deformation mechanism of commercial pure titanium foils

TL;DR: In this paper, the size effect on the tensile properties of commercial pure titanium foils with thickness ranging from 5´µm to 200´ µm has been investigated and two kinds of constitutive equations have been established in consideration of the grain size or the ratio of the thickness to grain size.
Journal ArticleDOI

Overview of JET results for optimising ITER operation

J. Mailloux, +1217 more
- 04 Jan 2022 - 
TL;DR: The ITER-like wall (ILW: Be wall and W divertor) installed in 2010, improved diagnostic capabilities now fully available, a major neutral beam injection upgrade providing record power in 2019-2020, and tested the technical and procedural preparation for safe operation with tritium as discussed by the authors .
Journal ArticleDOI

Oxidation resistance of bulk plasma-facing tungsten alloys

TL;DR: In this paper, the first wall of a DEMO-Fusion Reactor was studied at a temperature of 1273 k and the oxidation was measured at a rate of 1 × 10 − 6 mg cm − 2 s − 1.
Journal ArticleDOI

Beryllium migration and evolution of first wall surface composition in the JET ILW configuration

TL;DR: In this paper, the evolution of divertor surface composition resulting from wall material migration was observed at a similar time scale as previously observed in Be migration experiments in the JET carbon wall configuration.
