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,

通过焊接和钎焊等各种技术进行材料连接是制造和修复航空和发电涡轮的重要技术。 加拿大数十亿美元的航空航天工业的一项主要活动是通过不同的连接工艺制造和修理飞机和航空发动机部件。 不幸的是，大多数金属航空航天材料，如铝、钛和镍基超合金，难以焊接和钎焊，并且在加工过程中开裂。找到解决其连接问题的关键一步是通过彻底了解工艺参数对连接前和连接后材料微观结构的影响。 因此，我们认为，
