Investigation of Fatigue Performance of Additively Manufactured Freeform Components via Non-destructive Metrology

该项目旨在研究通过增材制造（AM）生产的高附加值自由形状部件的疲劳性能，例如涡轮机叶片和热交换器。这些具有复杂几何形状的AM部件的疲劳行为与AM工艺产生的表面形貌和内部缺陷高度相关。将利用非破坏性计量技术（X射线计算机断层扫描和焦点变化显微镜）来测量这些特性，并允许开发有限元模型来预测疲劳性能。

The project aims to investigate the fatigue performance of high-value-added freeform components produced by additive manufacturing (AM), such as turbine blades and heat exchangers. The fatigue behaviours of these AM components with complex geometries are highly related to surface topography and internal defects resulting from the AM process. Non-destructive metrology techniques (X-ray computed tomography and focus variation microscopy) will be utilised to measure these characteristics and allow a Finite Element Model to be developed for the prediction of the fatigue performance.
