Vanadium-based alloys show promise as structural materials for nuclear fusion reactors, due to their favourable properties, such as low reactivity, high thermal strength, and resistance to swelling.
Specifically, the alloy V-4Cr-4Ti (referred to as V44) is a leading candidate, offering solid solution strengthening from chromium and suppression of swelling and embrittlement through the addition of titanium.
To assess V44's mechanical characteristics, scientists from UKAEA and the University of Birmingham conducted in situ high energy X-ray diffraction (XRD) tensile testing at different temperatures to explore its potential as a structural material for nuclear fusion reactors.
