Developing multi-material structures using additive manufacturing

该博士项目的目标是解决金属功能材料（FMs）的知识差距，并建立多金属增材制造（AM）的新方法。这就需要为激光增材制造确定合适的材料组合，并为不同材料之间形成的界面确定合适的设计准则。为了金属调频的成功，有一个关键的需要了解如何不同的金属可以在增材制造中组合，以实现所需的性能。为了实现这一目标，该项目将专注于确定印刷部件的界面区域的结构和热行为，在那里不同的材料接触。这将通过研究打印激光参数对这些区域的影响来实现。同样，了解界面上不同的材料分布（尖锐分布、扩散分布、互锁分布等）如何影响接头的鲁棒性也是至关重要的。这些复杂部件的正确设计需要对打印结构中形成的界面进行表征和测试。

The objective of this PhD project is to address the knowledge gap around metallic Functional Material's (FMs) and establish new methods for multi-metal Additive Manufacturing (AM). This requires the identification of suitable material combinations for laser-based AM and the determination of appropriate design guidelines for the interfaces formed between dissimilar materials. For the success of metallic FM, there is a critical need to understand how different metals can be combined in AM to achieve desired properties. To achieve this, the project will focus on determining the structural and thermal behaviour of the interface regions of the printed component, where dissimilar materials are in contact. This will be done by studying the printing laser parameters' effect on these regions. Similarly, it is essential to understand how different material distributions at the interface (sharp distribution, diffused, interlocked, etc.) affect the robustness of the joint. The correct design of these complex parts will require characterizing and testing the interfaces formed in the printed structures.
