Grain extraction and microstructural analysis method for two-dimensional poly and quasicrystalline solids

Abstract: While the microscopic structure of defected solid crystalline materials has significant impact on their physical properties, efficient and accurate determination of a given polycrystalline microstructure remains a challenge. In this paper we present a highly generalizable and reliable variational method to achieve this goal for two-dimensional crystalline and quasicrystalline materials. The method is benchmarked and optimized successfully using a variety of large-scale systems of defected solids, including per… Show more

“…Motivated by some of the current developments in material sciences [33,62] and crystalline material image analysis [7,8,12,30,40,70] , we focus on two dimensional lattice, which plays major roles in crystallography [23,60], sampling theory [50], ecology [66] and many others. For example, crystal structures of halite (NaCl) and gold (Au) have distinct scales (NaCl constant: 5.640Å [26]; Au constant: 4.065Å [19]), which explains their proprietary differences.…”
