Description
・ケイ素:6.5〜10wt%
・マグネシウム:0.25〜0.35wt%
・銅:0.3〜0.7wt%
・ハフニウム:0.025〜0.55wt%
・ストロンチウム:0.0090〜0.0151wt%
任意に以下を添加する。
・チタン:0〜0.2wt%
・ジルコニウム:0〜0.3wt%
残りは、Alと、最大0.45wt%のFeを含む不可避の不純物とからなる。
475℃〜550℃(目標525℃)で5時間〜10時間(目標5時間)溶体化
(種々の媒質(主に水だが空気の場合もある)を用いて)急冷
180℃〜250℃(目標200℃)で2時間〜8時間(目標5時間)時効処理
クリープ実験を、ISO規格(2009年8月のEN ISO 204)に従って実施して、材料の挙動に対するHfを含有する析出物の影響を実証した。性能を、2つの他のAlSi鋳造用合金及び上述されるようなアルミニウム銅合金と比較した。
・他の通常のA356合金化元素に加えてジルコニウムを含有するII−2合金は、従来のA356(AlSi7Mg)合金よりも優れている。
・Al3Zr(Ti)分散質の存在を伴うAl5%CuであるIII−3合金は、II−2合金よりも優れている。
・通常のA356合金化元素に加えて0.5%のHfのみを含有するII−8合金は、III−3合金と類似した特性を示す。
・本発明による合金であるII−9合金は、最良のクリープ挙動を示す。この合金は、0.5%のHfに加えて0.5%の銅を含有する。この材料におけるハフニウムの添加がこの性能に主に関与し、このことはII−8合金の場合も同様であることが仮定される。II−9合金は僅かに多くのSiも含有するが、これはこの観点からは重要でないと考えられる。
室温での特性を従来の引張試験後に導出した。結果を、上述された合金のうちの1つであるA356と比較して以下の表2に示す。
