Titanium (Ti) is widely used in the aerospace and chemical industries owing to its excellent fatigue-allowable strength-to-weight ratio and good corrosion resistance1. However, it has a high affinity for hydrogen, and hydrogen pick-up is often associated with reductions in toughness and ductility2...
