Wire Arc Direct Energy Deposition of super alloys

这项研究将侧重于开发一种新的电弧增材制造（WAAM）设备，以提高先进金属合金的沉积性能。研究领域将包括使用多根电线来实现不同的材料性能，通过使用热和低温冷却来提高材料性能，并对WAAM工艺和熔池进行建模。此外，研究将确定适当的测试方法来分析沉积部件的材料特性。这些方法包括微观结构分析、拉伸测试和硬度测试。这种工作的好处很简单。随着生产接近净形状的能力，最大限度地减少浪费材料的能力是可能的。这有可能带来巨大的经济收益，也有内在的环境效益，因为它不会浪费太多的材料和能源。

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.
