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

全文：增材制造的金属部件的强度和表面微观结构，无论是制造和辐射/腐蚀环境因素的影响后。各种金属增材制造技术现在变得司空见惯。然而，假设增材制造的部件具有与传统部件相同的材料特性是错误的。在这个项目中，一系列的材料测试和多尺度特征将应用于标准的、低成本的3d打印（增材制造）金属部件。此外，这些部件将受到核工业中常见的腐蚀性环境的影响，例如腐蚀性液体和辐射。将分析由于这些环境损害而导致的表面微观结构、表面活化和辐射分解气体产量的变化。为了提高材料的性能，我们将研究不同印刷策略的效果。

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.
