Joining of materials by various techniques such as welding and brazing is an important technique to manufacture, and repair aero and power generation turbines. A major activity of Canada's multibillion-dollar aerospace industry is to manufacture and repair aircrafts and aero-engine components by different joining processes. Unfortunately, most of the metallic aerospace materials, such as aluminum, titanium, and nickel based superalloys are difficult to weld and braze, and crack during the process. A crucial step in finding solution for their joining problems is through a thorough understanding of the effect of processing parameters on microstructure of pre-joined and post-joined materials. Therefore,

通过焊接和悬挂等各种技术加入材料是制造以及维修航空和发电涡轮机的重要技术。 加拿大数十亿美元航空航天行业的一项重大活动是通过不同的加入流程来生产和维修飞机和航空发动机组件。 不幸的是，大多数金属航空航天材料（例如铝，钛和基于镍的超合金）在此过程中很难焊接和铜管，并且在此过程中破裂。找到解决方案的关键问题的关键步骤是对处理参数对前加入和后加入后材料微观结构的影响进行透彻理解。 所以，
