Severe plastic deformation of tungsten (W) is known to be an efficient way to reduce its inherently high ductile-to-brittle transition temperature (DBTT), what is essential for its use in components of a fusion reactor. Thin rolled W foils possess su

Properties extracted from uniaxial tension provide fundamental information about the strength and ductility as the first input for the structural analysis, conventionally performed by means of finite element computations. In recent years, there has b

In this contribution, we present the results of recent neutron irradiation campaign performed in the material test reactor BR2 (Belgium) on pure tungsten. We have applied various irradiation conditions and sample geometry to assess the effect of neut

In this work, we have investigated the evolution of the hardness of tungsten under successive thermal shock pulses induced under plasma exposure at quasi-stationary plasma accelerator QSPA-Kh50. The applied conditions represent localized modes of pla

Polycrystalline metals have flow stress two to three orders of magnitude lower than the theoretical shear strength estimated by Frenkel model. This significant strength difference is primarily due to the presence of defects, such as dislocations and

An original model is proposed in order to simulate elastic-plastic transients inside tungsten subjected to cyclic thermal loads expected due to plasma instabilities called “edge-localized modes” in ITER. The model assumes that plasticity is achie
