简要介绍了该聚合物合金的加工过程，其主要工艺是通过低温固相挤出和反应挤出制备。
The processing technology of this polymer alloy is briefly introduced. This polymer alloy is prepared by low temperature solid-state extrusion and reactive extrusion.
在铸坯凝固末端轻压下直接作用区域，两相区受到压缩，枝晶间富含溶质的液相被挤出，相对于铸坯向液芯方向流动。轻压下之后，铸坯中心区域由糊状区内被压缩的固相及残留的液相构成，中心区域偏析指数下降。
The simulation results show that mushy region is compressed and interdendritic solute-rich liquid flows toward the liquid core in the soft reduction action zone at the solidification end of the slab.
