开展了挤压加工对碳化硅颗粒增强铝基复合材料显微组织影响的实验研究 .结果表明 :挤压加工有助于细化增强颗粒并提高颗粒分布的均匀性 ;热挤压棒料中的增强颗粒沿挤压方向呈现定向、有序排列的特征 ;断裂颗粒不再成为损伤
The experimental research on the effect of extrusion processing on the microstructure of SiC matrix composites reinforced with SiC particles was carried out.The results show that the extrusion processing can help to refine the particles and improve the uniformity of the particles distribution. Reinforced particles along the extrusion direction orientation, ordered arrangement of features; fracture particles no longer become damage
