Abstract
Grain growth has significant effect on the material's microstructure and properties. In this thesis, the grain growth processes under the conditions of the second-phase particles (SPP) with different geometric orientations are studied by means of the phase-field method. The main results are as follows: 1. In the grain growth process, most of the spherical SPP locate at the intersection of crystal boundary, while stick SPP locate at the grain boundary with the same direction as the grain boundaries. 2. Under the condition that the SPP area fraction is constant, stick SPP in different orientations has little effect on the grain size. 3. Under the condition that the SPP area fraction and size are constants, there is no difference between stick SPP and spherical SPP in the pinning effect on grain growth when the area fraction of the SPP is small. 4. The SPP show a strong pinning effect on grain boundary and the limited grain radius can be expressed by Zener relations.
