Due to the rising cost of fuel, air travel has become a very cost sensitive industry. To remain globallycompetitive, aero engine manufacturers such as Pratt and Whitney Canada (P&WC) have increasingly focusedon reducing manufacturing costs. A contributor to the cost of gas turbine engines is a high buy-to-fly ratio(BTF) resulting from a heavy reliance of traditional manufacturing methods on material removal and waste (i.e.machining of wrought billets). Primary metal production is a significant contributor to the production ofgreenhouse gases and the Ni and Cr elements contained within engine parts are non renewable limitedresources. Therefore a high BTF has a significant negative environmental impact.Aerospace companies are adopting more near net shape (NS) manufacturing to reduce BTF, overallmanufacturing costs and develop green technologies. P&WC is pursuing a net shape method which combinesfurnace brazing with powder injected molding (PIM). The challenge is to create PIM parts and brazed jointsthat have mechanical properties and performance equal to parts made using traditional manufacturing methods.The goal of this research program is to develop and use a number of advanced thermal analysis techniques togain a fundamental understanding of Ni-based superalloy brazing and PIM processing. This thermal analysiswill be used to develop processing techniques which avoid the formation of detrimental boride compounds andporosity in the brazed joint. The analysis will also develop a deep understanding of the changes taking placeduring debinding, sintering and heat treatment of PIM parts.This program will allow P&WC to extend NS processing to the structural parts of their engine manufacturingoperations, thus decreasing the BTF, cost and material waste. This will lead to a more competitive Canadianaerospace industry and economy, the development of green manufacturing technologies and an improvedenvironment. Thirteen highly qualified professionals will be trained during the program, who will contribute tothe aerospace industry for decades to come.

由于燃料成本上升，航空旅行已成为一个非常敏感的行业。为了保持全球竞争，Pratt和Whitney Canada（P＆WC）等航空发动机制造商越来越重点降低制造成本。燃气轮机发动机成本的一个贡献者是高购买比率（BTF），这是由于对传统制造方法的材料清除和废物（即锻造钢轮的手机）的严重依赖而产生的。一级金属生产是绿色屋气体生产的重要贡献，发动机零件中包含的Ni和Cr元素是不可再生的有限用量。因此，高BTF具有显着的负面环境影响。大型航天公司正在采用更多接近净形状（NS）制造业来降低BTF，整体制造成本和开发绿色技术。 P＆WC正在采用一种净形方法，该方法将Furnace Furnace与粉末注入的成型（PIM）结合在一起。面临的挑战是创建PIM零件和悬挂的关节，这具有机械性能和性能，等于使用传统制造方法制造的部分。该研究计划的目标是开发和使用许多先进的热分析技术，对基于NI的Superalloy Brazing和Pim处理有了基本的理解。该热分析将用于开发加工技术，以避免形成有害的硼化物化合物和悬挂关节中的孢子。该分析还将对PIM零件的删除，烧结和热处理的变化有深入的了解。该计划将使P＆WC将NS处理扩展到其发动机制造业的结构部分，从而减少BTF，成本和材料浪费。这将导致更具竞争力的加拿大竞争行业和经济，绿色制造技术的发展以及改善环境。该计划期间将对13名高素质的专业人员进行培训，他们将在未来几十年内为航空航天行业贡献。
