【摘要】：Zr元素在超高強鋁合金中的應(yīng)用可以追溯到B96鋁合金,Zr元素已成為超高強鋁合金中不可缺少的微量元素。本實驗分別采用Al-Zr中間合金、氟鋯酸鉀和復(fù)合鋯鹽3種工藝加入Zr元素,研究了熔煉溫度對Zr元素收得率和凝固組織的影響,熔煉溫度及加入工藝對Zr元素存在形式的影響。結(jié)果表明:采用復(fù)合鋯鹽加入法,Zr元素的收得率最高,細化效果最好。在750℃采用Al-Zr中間合金加入法,試樣中含Zr相較為粗大,組織細化效果不好。
[Abstract]:The application of Zr element in ultra-high strength aluminum alloy can be traced back to the fact that Zr element of B96 aluminum alloy has become an indispensable trace element in super high strength aluminum alloy. Al-Zr master alloy was used in this experiment. The effect of melting temperature on the yield and solidification structure of Zr was studied by adding Zr elements in three processes: potassium fluorozirconate and complex zirconium salt. The effect of melting temperature and adding process on the form of Zr element was studied. The results showed that the yield of Zr element was the highest by adding the compound zirconium salt. The best refining effect was obtained by adding Al-Zr master alloy at 750 鈩，
