Evolution of topological microstructures during irradiation in Ti alloys for particle accelerator facilities and fusion reactors.

具有复杂拓扑结构的钛合金是粒子加速器中的重要材料，在聚变反应堆特别是热沉元件中具有重要的应用价值。然而，有关其耐辐射性的数据非常稀少，处于不令人满意的阶段。这个博士项目的目的是有助于理解在先进的钛合金使用高能质子辐射辐照下的拓扑微结构的退化。这项工作将导致新的钛合金的拓扑微结构设计具有上级耐辐照性。

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.
