摘要
探讨了液固挤压SiCp/LY12复合材料的组织与性能特征及其相互之间的关系。研究表明 ,其基体组织晶粒细小 ,SiC颗粒基本呈均匀随机分布 ,无明显堆积及脱粘现象 ,且与基体结合良好 ;抗拉强度比基体材料提高 2 0 %～ 32 %。从而为颗粒增强金属基复合材料管、棒材的制备提供了一种减少工序、节能节材的可行方法。
The characteristics of microstructure and properties of SiC p/LY12 composite prepared by liquid solid extrusion process and their mutual relation were discussed. The results show that the grains of matrix are refined and SiC particles distribute evenly and randomly. There exists no collection of SiC particles. The bonding among the particles and matrix is strong. Compared with the matrix alloy, the tensile strength increases by 20%～32%. These results prove that the liquid solid extrusion process is an effective method for manufacturing tube and bar products of metal matrix composites reinforced by particles.
