摘要
细晶铝锭是采用纯铝的电解设备,通过向铝电解槽中添加TiO2,直接电解生产的晶粒细化的铝锭。采用细晶铝锭熔的6063铝合金与AlTi5B1、AlTi5中间合金细化的6063铝合金铸态组织性能进行对比研究。结果表明:AlTi5B1中间合金细化效果最好,AlTi5中间合金细化效果最差,细晶铝锭的细化效果居中;6063铝合金铸态组织硬度,在钛含量低于0.05%时,主要由Mg2Si含量决定,晶粒大小对硬度的影响较小。
Grain-refining aluminium ingots are produced by electrolysis, through adding TiO2 into electrolyzing cell. This paper has researched as-cast microstructures and properties of 6063 Aluminium alloys melted with grain-refining aluminium ingots, contrasting with other grain-refining methods, such as with AlTi5, AlTi5B1 master alloys. The results shows： the AlTi5B1 master alloys have best grain refining effects, the AlTi5 master alloys have worse grain refining effects, grain-refining aluminium ingots is in the middle. The hardness of 6063 Aluminium alloys is depended on the contents of Mg2Si, regardless of grain diameters, when the contents of titanium are lower than 0.05%.
