Tungsten and tungsten-based alloys are the leading material choices for the divertor plasma
facing components (PFCs) in future fusion reactors. Recrystallization may occur when they …

Extending the lifetime of tungsten based plasma facing components for future fusion reactors
remains an everlasting challenge. In this work, the microstructure of tungsten monoblocks …

Helium plasma is known to affect recrystallization in tungsten, with lower temperatures
during plasma exposure leading to slower crystal grain growth. To understand why this …

Tungsten has been chosen as the main candidate for plasma facing components (PFCs)
due to its superior properties under extreme operating conditions in future nuclear fusion …

High ductile-to-brittle transition temperature, recrystallization-induced embrittlement, and
neutron-irradiation-induced embrittlement are potential drawbacks related to the mechanical …

To investigate the behaviors of tungsten based plasma facing materials under fusion
relevant transient heat flux, two kinds of commercial tungsten materials processed with and …

A high-repetition-rate ELM simulation system was used at both the Pilot-PSI and Magnum-
PSI linear plasma devices to investigate the nature of W damage under multiple shallow …

Surface damage and structure evolution of the full tungsten ITER divertor under transient
heat loads is a key concern for component lifetime and plasma operations. Recrystallization …

In the future fusion devices, ELMs-induced transient heat flux may lead to the surface
cracking of tungsten (W) based plasma-facing materials (PFMs). In theory, the cracking is …

The plasma facing unit (PFU) of ITER divertor is repeatedly exposed to high heat flux, and a
reliable heat removal capability is crucial for its adequate performance. The cyclic high heat …
