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

在这个EngD项目中，一个关键的目标是：(1)开发一种低成本、快速的钛合金零件可加工性评估技术，该技术适用于通过常规锻造工艺和新兴粉末工艺(如添加剂制造)生产的钛合金部件，这些工艺会产生一系列不同的组织和织构。另一个目标是(2)了解微观结构和织构对亚表面损伤和刀具寿命的影响。该公司的长期目标是开发数字双胞胎，用新的合金化学成分和纹理模拟新的工具溶液，并可靠地预测可能导致使用中机械性能较差的损伤累积。例如，部件可以是髋关节或气动结构部件，我们将与这些各自行业的供应链合作，开发这些数字双胞胎。

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.
