Tungsten is a promising material for the plasma-facing components of nuclear fusion
reactors due to its resistance to heat flux and plasma influence. However, a transient heating …

One of the challenges in fusion reactors is the discovery of plasma facing materials capable
of withstanding extreme conditions, such as radiation damage and high heat flux …

Tungsten materials are subjected to severe damage when exposed to transient high heat
loads, and the crack initiation and propagation are observed experimentally based on the …

Understanding the behavior of tungsten (W) surface damage under the synergistic effects of
high heat flux (HHF) loading and helium (He) irradiation is essential for predicting material …

In this paper, using laser direct writing technology, a femtosecond laser was used to process
a periodic grating structure on a 99.99% tungsten target. The specific parameters of the laser …

Tungsten and tungsten carbide were damaged in ambient air with varying incident angles
(0, 30, 45, and 60 deg) for approximately 5000 shots. The goal of these experiments was to …
