Abstract Aiming at the manufacture technology of aeroengine single crystal turbine blades and recrystallization
defect, combined with the research status at home and abroad, from the single crystal hollow turbine blade casting technology,
single crystal hollow turbine blade recrystallization defect and control method of single crystal blades recrystallization,
etc., the manufacture technology and recrystallization control methods to obtain the research results are summarized and
analyzed. It focuses on the manufacture technology of the blade and recrystallization control technology and the research.
Combined with the above analysis, further research of the manufacture technology of the single crystal hollow turbine blade
and recrystallization defect as a priority is analyzed.
