【摘要】 描述了一种轴向挤压的半固态合金浆料的数学模型.半固态合金浆料的固相和液相可以相互邻接,它们的变形行为可以藕合.固相的增稠控制着流体流动行为,由此得到在液相中分布的压力可能会影响固相的增稠和液相的偏析.模型可以用来预测半固态合金试样径向上的液相体积分数的分布情况.更多还原

【Abstract】 A mathematical model of axisymmetric compression of semi-solid alloy slurry was described.The model is applicable to conditions where the solid and liquid phases may be contiguous and their deformation behaviors are coupled.The densification of the solid skeleton drives the fluid flow behavior,and the resulting pressure distribution in the liquid affects the densification in the solid and the liquid phase segregation.The model can predict radial distribution of liquid fraction of semi-solid alloy slurry,specimen.更多还原
