Due to multiple specifications and variety of metallic materials of aviation industry such as steel, aluminum alloy and titanium alloy etc, heat treatment process of metallic materials has high quality requirement and is complex. With increasing attention on heat treatment in aviation manufacture factories, many long existing problems have been resolved gradually. Compared with emphasis on results and qualification rate of heat treatment previously, more importance should be attached to process parameter control and existing data potentiality exploitation. This thesis briefly describes heat treatment of a few types of metallic materials, puts forward some problems and simple analysis, and proposes some improvement suggestions for the reference of related personnel.
