The present invention relates to a substrate-triggered single crystal superalloy directional solidification process, including: (1) preparing a single crystal substrate material having crystallographic characteristics that match crystallographic characteristics of the single crystal superalloy; (2) fabricating a single crystal substrate chilling plate using the obtained single crystal substrate material; and (3) applying the obtained single crystal substrate chilling plate in a directional solidification apparatus, and then preparing a single crystal alloy product by performing superalloy melting and directional solidification. Compared with grain selector method and seeding with grain selector method, in addition to control the crystallographic orientation of the single crystal superalloy precisely, the present invention could reduce the height of block and the whole mold through canceling the spiral grain selector, significantly improve the axial heat dissipation and temperature gradient at the solid-liquid interface, and then reduce the occurrence of freckles and stray grains near platform.

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.
