高γ '镍基高温合金的增材制造（AM）是将新型部件几何形状引入燃气涡轮机动力装置核心的关键推动因素。这些合金在凝固期间经历的冷却速率直接决定了提供可接受的特征分布和可接受的微观结构的制造工艺窗口。该项目将对粉末床和直接能量沉积AM工艺进行原位束线实验，以研究一系列合金系统的凝固行为。实验数据将被纳入正在为这些过程开发的过程模型，该项目将涉及一些使用和修改这些models.The新的工程内容的研究是在原位同步辐射成像AM使用高伽玛'镍基高温合金，和AM过程建模。

Additive Manufacturing (AM) of high gamma prime nickel-based superalloys is a key enabler for introducing novel component geometries into the core of gas turbine powerplants. The cooling rate these alloys experience during solidification directly determines the manufacturing process window which provides acceptable feature distribution and acceptable microstructures. This project will perform in-situ beamline experiments for both powder bed and direct energy deposition AM processes to investigate the solidification behaviour of a range of alloy systems. The experimental data will be incorporated into process models being developed for these processes and the project will involve some use and modification of these models.The novel engineering content of the research is in-situ synchrotron imaging of AM using high gamma prime nickel-based superalloys, and AM process modelling.
