Development of machining digital twins that predict microstructural damage and service life for a range of titanium alloy processing routes

在该EngD项目中，主要目标是（1）为传统锻造路线和新兴粉末路线（如增材制造）生产的钛合金部件开发一种低成本和快速的可加工性评估技术，这些路线产生一系列不同的微观结构和纹理。另一个目的是（2）了解亚表面损伤和刀具寿命的微观结构和纹理的影响。长期目标是开发数字孪生模型，模拟具有新合金化学和纹理的新工具解决方案，并可靠地预测可能导致使用中机械性能差的损伤累积。例如，该组件可以是髋关节或航空结构部件，我们将与这些相应行业的供应链合作开发这些数字孪生模型。

In this EngD project a key aim will be to (1) develop a low-cost and rapid machinability evaluation technique for titanium alloy components produced by convention forging routes and emerging powderroutes (such as additive manufacturing), which generate a range of different microstructures and textures. Another aim will be to (2) understand the effect of microstructure and texture of subsurface damage and tool life. The long term ambition is to develop digital twins that simulate new tool solutions with new alloy chemistries and textures and reliably predict damage accumulation that could lead to poor mechanical performance in service. The component could be, for example, a hip joint or aerostructural part and we will collaborate with the supply chain of these respective industry sectors to develop these digital twins.
