摘　　要：采用铝热还原法工艺制备AlTiC中间合金,通过X射线及扫描电镜(SEM)等分析了AlTiC中间合金的成分、组成和形貌。利用自行研制的AlTiC中间合金对工业纯铝的细化进行研究,借助于光学显微镜(OM)等手段对细化效果进行了分析对比,并初步探讨了其细化效果的机理。试验结果表明,与国产AlTiB中间合金相比,AlTiC中间合金对工业纯铝的细化效果较优。AlTiC master alloys were prepared by aluminum-thermal reduction.Analysis is made of the composition,microstructure and morphology of the AlTiC master alloys through X-ray diffraction（XRD） and scanning electron microscopy（SEM）.Study is made of the refinement of the commercial pure Al by the self-developed AlTiC grain master alloy and the refining results are analyzed and compared through optical microscope and refining mechanism is preliminarily discussed.The test results show that the refining effect of AlTiC master alloy is better than that of the domestic AlTiB master alloy.
