【摘要】 采用颗粒纯钛法制备新型的Al-Ti-B-RE中间合金,为提高铝制品的质量和降低成本,在稀释熔融状态下对工业纯铝进行细化处理。借助于扫描电镜(SEM)、光学显微镜(OM)等手段对其晶粒细化效果进行分析对比。细化实验表明,稀释后Al-Ti-B-RE中间合金在较短的时间内就具有较好的晶粒细化效果,要优于的AlTiB中间合金。更多还原

【Abstract】 Al-Ti-B-Re master alloy has been prepared by adding of pure Ti grain.For improving the quality and reducing the cost of aluminum products,the Al-Ti-B-Re master alloy is added to refine industry pure Al in molten state and diluted.Analysis and comparison of the refining effects are conducted by scanning electron microscopy(SEM) and optical microscopy.The result shows: Al-Ti-B-Re has good and quick grain refining effect when added in molten state.Experimental results indicate that the self prepared AlTiC grain refiner shows obvious advantages over the AlTiB grain refiner in domestic.更多还原
