Development of nickel based superalloys for additive repair applications

旨在了解镍基高温合金的可焊性，并在此基础上开发新合金，或对现有合金进行修改，以用于修复应用;即材料添加（MA）。因此，该项目将寻求了解为所需应用优化镍基高温合金化学所需的步骤。需要研究和了解镍基高温合金中不同元素的影响，以便明确化学品的工艺窗口及其对修复可焊性的影响。除此之外，还需要清楚地了解不同的修复工艺和条件如何影响所得微观结构和性能上的化学和几何形状。

Aim to understand the weldabilty of nickel-based superalloys and build on this knowledge to develop new alloys, or modifications to existing alloys, enabling use for repair applications; namely Material Addition (MA). As such, this project will seek to understand the steps required to optimise the chemistries of nickel-based superalloys for the desired application. The influence of the different elements within the nickel-based superalloys will need to be researched and understood so that the process window of chemistries and their effects on weldability for repair are clear. In addition to this, a clear understanding of how different repair processes and conditions affect chemistries and geometries on the resulting microstructure and properties is desired.
