摘要
利用有限元软件模拟WCu合金的熔渗过程。根据W颗粒骨架实际形貌,建立了球形颗粒堆积骨架模型;在等径与非等径多孔体系内部,分析了铜液在渗流路径中的压力及速度矢量分布;得出了当W粉平均粒度为5μm时,铜液在多孔体系内部的熔渗深度与熔渗时间的关系,模拟结果与实验相符。
The process of melt infiltration of WCu alloy was simulated by the finite element software. A spherical particle skeleton model was established according to the distributing morphology of W particles. The pressure and the velocity vector distribution of copper liquid in the flow path were analyzed in isodiametric and non-isodiametric porous system. The relationship between the depth and time of infiltration in the porous system is obtained when the average particle size of W powder is 5 μm, which is in good agreement with experimental values.
