摘要

Stray grains (SGs) in the platform region of the Ni-base single crystal turbine blades are deleterious to the mechanical properties in service, therefore the formation of SG may directly cause the rejection of the castings. This paper reviews the researches on the origin, mechanism and influencing factors of stray grain formation in the platform region. Several controlling techniques and their mechanism on SG control are also summarized. The current existing problem and future research aspects are stated and discussed as well.
