摘要	The effect of solidification rate on grain structure evolution during directional solidification (DS) of a Ni-based superalloy was explored. It was found that a high solidification rate led to sharper < 001 > texture and smaller grain size in the DS samples. One of the most important findings in this work was that such result was not in accordance with the general concept, and the sharper < 001 > texture was accompanied by the larger grain size. To explain the contradiction, the modeling samples with five grains were produced and the effect of solidification rate on the evolution of grain texture was illustrated based on the modeling samples.
