摘要

采用元胞自动机方法（Cellular Automation Method）模拟铝带铸轧过程中晶粒的生长

模拟过程中用简化的二元合金模拟了过冷熔体中枝晶的生长

且过冷熔体中枝晶的生长模型采用LGK模型。在枝晶生长的基础上模拟了铝带在铸轧过程中冷却及铸轧速度引发的过冷度对晶粒生长的影响。结果表明

在形核率一定的情况下

过冷度越大

晶粒越大。

Abstract

Grain growth in aluminum strip during rolling was simulated by the cellular automaton method

in which the dendritic growth in super-cooled melt was considered based on simplified binary alloy by means of LGK model. Effects of cooling rate and super-cooled rate derived from rolling velocity on grain growth were simulated by the model. The results show that

with increasing in super-cooled rate

the grain size is increased at a given nucleation rate.
