摘要
用中断挤压铸造法研究了ZL109合金液在莫来石纤维预制块中的流动状况。发现微观上流动前沿存在许多合金液的“包抄”,这种包抄可能导致孔洞的形成;讨论了复合材料中孔洞的形成模型,分析了预制块中纤维间最小间隙在形成孔洞中的作用。
The flow front of ZL109 melt in mullite chopped fibre preform during melt infiltration was investigated with a method called stopping squeeze casting. It was found that there are a number of“outflankings” in the flow front, which can result in the formation of pores in the composite. A modeling of pore forming and the influence of the minimum interspaces on pore forming was analyzed and discussed also.
