Titanium alloys with complicated topological microstructures are essential materials in the particle accelerator facilities, and are attractive for fusion reactors, particularly for heat sink elements. However, data related to its radiation resistance are very sparse and is at an unsatisfactory stage. The aim of this PhD project is to contribute to the understanding of degradation of topological microstructure under irradiation in advanced Ti alloys using high energy proton radiation. The work will lead to topological microstructural design of new Ti alloys with superior irradiation resistance.
