新一代Al-Ti-C晶粒细化剂的工业应用

最近的研究证明,AlTiC晶粒细化剂不存在与AlTiB中TiB2有关的缺点,TiC聚集倾向小和对锆、铬中毒免疫.介绍了研制的新型AlTiC晶粒细化剂的实验室试验和工业应用试验结果.对99.7%Al的实验室试验表明AlTiC的晶粒细化效果比进口AlTiB的好.在纯铝铸轧板的初步试用中也获得了良好的结果,在A356合金中已获得了工业应用.

The Application of New Generation of Al-Ti-C Grain Refiners

Recent investigations have shown that A1 - Ti - C grain refiners are less prone to the disadventages associated with TiB2 in A1 -Ti - B, TiC shows a reduced tendency to agglomaration and immunity to poisoning by Zr or Cr. This paper describes the results of laboratory tests and industry application tacts of the new A1 -Ti -C developed by us. Laboratory tests for 99.7% A1 have been shown that the refining results of our A1TiC are finer than the import A1TiB. A good results have achived in tests for aluminium casting sheet and A356 alloy.
