本文研究了用双辊铸机生产的ＳｉＣｐ／Ａ３５６复合材料薄带中ＳｉＣ的分布规律，着重分析了ＳｉＣ颗粒的体积分数（３％～１６％）和薄带的铸造速度（０．５～１０ｍ／ｍｉｎ）对ＳｉＣ颗粒分布均匀性的影响，结果表明，较高的ＳｉＣ含量或较高的铸造速度均可抑制薄带表面贫ＳｉＣ层的形成。
In this paper, the distribution of SiC in SiCp / A356 composite strip produced by twin roll caster is studied. The effects of SiC particle volume fraction (3% ~ 16%) and strip casting speed (0.5 ~ 10m / Min) on the uniformity of the SiC particles. The results show that the formation of SiC-poor layer on the surface of the ribbon can be suppressed by higher SiC content or higher casting speed.
