Research Progress on Grain Boundary Defects of Single Crystal Superalloy
With the increasing complexity of the turbine blade structure,the grain boundary defect becomes more and more difficult to control.Therefore,the study of grain boundary defects in single crystal superalloys has become a hot spot in the research of single crystal.In this paper,the causes of the grain boundary defects of single crystal superalloys are studied,and the influence of small angle grain boundary on the properties of alloys is summarized.Research progress on increasing the damage tolerance of alloy by adding trace elements are summarized,the future research direction is also proposed.
