| 英文摘要 | We perform three-dimensional phase-field simulations of equiaxed solidification in Al-Cu thin samples. Purely diffusive conditions are considered in order to describe systems where convection and gravity effects can be neglected. The use of a parallel adaptive finite element algorithmintroduced recently [Gong et al., Comput. Mater. Sci. 147 (2018) p. 338-352] allows us to reach the domain of copper concentrations used in practical applications (c >= 3 wt% Cu). We compare the present results with those of a previous study which was restricted to lower copper concentrations (c <= 2 wt% Cu) [Boukellal et al., Materialia 1 (2018) p. 62-69] due to the use of a finite difference code. In the fast dendritic growth regime, our results confirm that the dimensionless growth length. is independent of the copper concentration and the average separation distance between the dendrite nuclei. The new data obtained at higher copper concentrations lead to a more accurate estimate of.. Physical arguments are developed to specify the meaning of. and the grounds of the scaling law.= cst. Comparisons with available experimental results of the literature give additional support to this scaling law. |
