Titanium alloys can be used as fusion reactor structural materials, due to their interesting properties. Neutron-induced radioactivity in a Ti-6Al-4V alloy, when exposed to the neutron flux at a fusion reactor first wall, was analysed and found to be suitable for the management and disposal of radioactive wastes from a fusion reactor. This does not apply to presently available steels. The mechanical properties of two types of structure of a Ti-6Al-4V alloy were investigated - the fully recrystallised annealed condition and the solution-treated and aged condition. The influence of strain rate and temperature were also taken into account. The superplasticity of the alloy is a particularly interesting property, in view of the production of complex shapes for the first wall components of a fusion reactor.
