Strength and surface microstructure of additively manufactured metal components(full title below)

全标题：添加制造的金属部件的强度和表面微结构，无论是在制造时还是在辐射/腐蚀环境因素的影响之后。各种金属添加制造技术现在变得普遍。然而，假设添加制造的部件与其传统对应部件具有相同的材料特性将是错误的。在这个项目中，一系列材料测试和多尺度特征将应用于标准的、低成本的3D打印(添加制造)金属部件。此外，这些部件将受到核工业中常见的侵蚀性环境的影响，如腐蚀性液体和辐射。将分析由于这些环境危害而引起的表面微结构、表面活化和辐射分解气体产生的变化。将研究不同印刷策略的影响，以期改善材料性能。

Full Title: Strength and surface microstructure of additively manufactured metal components, both as manufactured and after the impact of radiation/corrosion environmental factors.Various additive manufacturing techniques for metals are now becoming commonplace. However, it would be a mistake to assume that additively manufactured components had the same material properties as their traditional counterparts. In this project, a range of material tests and multi-scale characterisations will be applied to standard, low-cost 3D-printed (additively manufactured) metallic components. Additionally, these components will be subjected to the aggressive environments commonly found in the nuclear industry, such as corrosive liquids and radiation. Changes in the surface microstructure, surface activation and radiolytic gas production due to these environmental insults will be analysed. Effects of different print strategies will be investigated with a view to improving material performance.
