Simulation of grain coarsening using one-dimensional cellular automaton

Numerous simulation methods were developed to simulate the grain growth process in metals and alloys. The basis of these methods is the modeling of the properties and the movement of grain boundaries. From this size level in all solution could be get the microscopic nature of grain growth. One of the simulation methods is the cellular automaton. The simplest cellular automata are the one-dimensional cellular automata. In one-dimension all the properties of the grain boundaries cannot be taken into consideration. This article shows the scale and a method which makes the onedimensional cellular automaton suitable to simulate the grain coarsening process. The average grain size of a Cu18Ni20Zn alloy was measured during an isothermal heat treatment as a function of time and temperature. The results of the simulation are scaled to the measured values, and fit one to another. © (2013) Trans Tech Publications, Switzerland.
