摘要
研究了Al-5Ti-1B和Al-3Ti-0.15C两种细化剂对2026铝合金铸锭组织、型材组织及型材性能的影响。结果表明,在0.2%的添加量下,Al-5Ti-1B细化剂的细化效果优于Al-3Ti-0.15C细化剂,采用Al-5Ti-1B细化剂生产的铸锭和型材的晶粒尺寸均小于对比试样;采用Al-5Ti-1B细化剂生产的型材强度略高于采用Al-3Ti-0.15C细化剂生产的型材,但伸长率略有降低。
The effects of two imported refiners,Al-5Ti-1Band Al-3Ti-0.15C,on the microstructure of 2026ingots and extrusion profile as well as extrusions properties were investigated.The results reveal that the refinement effect of Al-5Ti-1Bgrain refiner is better than that of Al-3Ti-0.15Cgrain refiner at the same amount of 0.2%addition.The grain size of ingots and extrusions adding Al-5Ti-1Bgrain refiner is smaller than that of the comparative sample.The strength of extrusion profile adding Al-5Ti-1Bgrain refiner is slightly higher than that of one adding Al-3Ti-0.15Cgrain refiner,while the elongation is reduced slightly.
