建立偏晶合金液—液两相区内第二相液滴碰撞粗化的数学模型.并对Zn-Pb合金作数值模拟计算.结果表明,当第二相液滴平均半径<1μm时,布朗凝并起主要作用,当第二相液滴平均半径较大时,重力凝并起主要作用.
A synthetical mathematical model describing the collision coarsening of the second phase droplets in the liquid-liquid temperature range of monotectic alloys has been put forward. Numerical simulation has hen carried out for Zn-Ph alloy. It was found that
