Wire Arc Direct Energy Deposition of super alloys

这项研究将专注于开发一种新的电弧增材制造（WAAM）设施，以提高先进金属合金的沉积性能。调查领域将包括使用多根线材以实现不同的材料特性，通过使用热和低温冷却来提高材料性能的热性能，以及WAAM工艺和熔池的建模。此外，研究将确定适当的测试方法，用于分析沉积部件的材料特性。这些方法包括显微组织分析、拉伸试验和硬度试验。由于能够生产近净形状，因此能够最大限度地减少浪费的材料。这具有显著的经济收益潜力，以及通过不浪费尽可能多的材料和能源而产生的固有环境效益。

This research will focus on development of a new Wire Arc Additive Manufacturing (WAAM) facility to enable increase deposition performance of advanced metal alloys. Areas of investigation will cover the use of multiple wires to enable different material properties , thermal performance through both the use of heat and cryogenic cooling to improve material performance and modelling of the WAAM process and melt pool. In addition the research will identify appropriate testing methods for analysing material properties of the deposited parts. Such methods will include the analysis of microstructure, tensile testing and hardness testing.The benefit of such work is simple. With the ability to produce near net shapes the ability to minimise wasted material is possible. This has potential for significant financial gains as well as an inherent environmental benefit by not wasting as much material and energy.
