Patent number: 12023729Abstract: The present invention discloses a directional solidification method for a superalloy single crystal blade based on solid-liquid interface steady control. The method establishes effective criteria for withdrawal speed adjustment, i.e. the related position between a macro solid-liquid interface and a thermal baffle, the range between the dendrite tips at the solid-liquid interface, and the difference between the advance speed of the macro solid-liquid interface and the withdrawal speed. With these criteria, the advance of the solid-liquid interface during directional solidification is simulated and a withdrawal speed curve v(t) for the solid-liquid interface steady advancement was obtained. And then, the single crystal blade was prepared.Type: GrantFiled: January 5, 2021Date of Patent: July 2, 2024Assignee: Shanghai Jiao Tong UniversityInventors: Long Zeng, Jun Li, Mingxu Xia, Neng Ren, Binqiang Wang, Jianguo Li
