在此基础上采用有限单元方法数值求解模型，并运用热焓法处理凝固潜热，得到了一定工艺条件下的稳态凝固温度场。
Using enthalpy to deal with latent heat of solidification the numerical model is solved by finite element method, and a steady temperature field can be obtained under a certain condition.
氢气分压一定，选择合适的氩气分压可使熔体共晶凝固时，孔尺寸、孔位置和气孔结构单元的分布最均匀。
The results show that at pure hydrogen atmosphere, the uniformity of pore size, spatial distribution of pores and por…
