| Abstract Scope |
It is well known that the properties of ceramics can be improved by tailoring the texture. For example, lamellar textured ceramics have high thermal conductivity along the lamella and good mechanical properties in the perpendicular direction. Templated grain growth (TGG) is a powerful texturing method. However, as microstructure evolution is strongly affected by various factors, such as matrix particle size, template particle size, and aspect ratio, it is difficult to experimentally determine these parameters to obtain an optimal microstructure. Multi-phase-field sintering (MPFS) simulator [Nakazawa et al. 2025], which can continuously reproduce from powder compaction to sintering for arbitrarily shaped particles, is a powerful tool to investigate effect of those parameters on TGG. Using the MPFS, we performed large-scale 3D TGG simulations by changing size and shape of matrix and template particles systematically, and investigated what is the dominant effect on the formation of texture microstructure. |
