Direct numerical simulation of homogeneous nucleation and growth in a phase-field model using cell dynamics method
Masao Iwamatsu
Homogeneous nucleation and growth in a simplest two-dimensional phase field model is numerically studied using the cell dynamics method. Whole process from nucleation to growth is…
Lowest-energy structures of 13-atom binary clusters: Do icosahedral clusters exist in binary liquid alloys?
M. Iwamatsu, S. K. Lai
Although the existence of 13-atom icosahedral clusters in one-component close-packed undercooled liquids was predicted more than half a century ago by Frank, the existence of such…
Scenarios of heterogeneous nucleation and growth studied by cell dynamics simulation
Masao Iwamatsu
The dynamics of phase transformation due to homogeneous nucleation has long been analyzed using the classic Kolmogorov-Johnson-Mehl-Avrami (KJMA) theory. However, the dynamics of p…
Cell Dynamics Simulation of Kolmogorov-Johnson-Mehl-Avrami Kinetics of Phase Transformation
Masao Iwamatsu, Masato Nakamura
In this study, we use the cell dynamics method to test the validity of the Kormogorov-Johnson-Mehl-Avrami (KJMA) theory of phase transformation. This cell dynamics method is simila…
Cell dynamics approach to the formation of metastable phases during phase transformation
M. Iwamatsu
In this paper, we use the cell dynamics method to study the dynamics of phase transformation when three phases exist. The system we study is a two-dimensional system. The system is…
Basin Hopping with Occasional Jumping
Masao Iwamatsu, Yutaka Okabe
Basin-Hopping (BH) or Monte-Carlo Minimization (MCM) is so far the most reliable algorithms in chemical physics to search for the lowest-energy structure of atomic clusters and mac…
