め注湯温度Ｔは，例えば，７２０℃≦Ｔ≦７３０℃に設
定される。When a large thin casting is cast by the die casting method, a higher pouring temperature (liquidus temperature + superheating temperature) is preferable from the viewpoint of maintaining the fluidity of the molten metal, but Al-Mg is preferable. When the pouring temperature T is set high in a molten alloy having a system-based alloy composition, the concentration of Mg in the molten metal decreases drastically due to the oxidation of Mg, etc., and seizure of the molten metal on the mold easily occurs , Causes problems. Therefore, the pouring temperature T is set to 720 ° C. ≦ T ≦ 730 ° C., for example.

を招来することになる。On the other hand, the finer crystal grains due to Ti and Zr are more effective if the added amount of them is large. However, even if they are increased excessively, Ti and the like are saturated at the pouring temperature T. Then, precipitation of crystallized substances such as Al 3 Ti and Al 3 Zr will be caused.

When / Zr is specified, at the pouring temperature as described above, the total amount of Ti and Zr contributes to the refinement of the crystal to increase the toughness of the Al-Mg-based alloy and also to cause precipitation of crystallized substances. Can be avoided.
【０００８】各化学成分の添加理由，添加量限定理由等
は次の通りである。The reasons for adding each chemical component and the reasons for limiting the amount added are as follows.
【０００９】Ｍｇ：Ｍｇは鋳物の強度および靱性の向上
に寄与する。ただし，Ｍｇ＜３．５ｗｔ％では溶湯の流
動性が悪化し，一方，Ｍｇ＞４．５ｗｔ％では鋳物の靱
性が低下し，また凝固が遅れた部分にＡｌ−Ｍｇ共晶金
属間化合物が偏析して鋳造割れを招来する。Mg: Mg contributes to the improvement of strength and toughness of the casting. However, when Mg <3.5 wt%, the fluidity of the molten metal deteriorates, while when Mg> 4.5 wt%, the toughness of the casting decreases, and the Al-Mg eutectic intermetallic compound segregates in the portion where solidification is delayed. And cause casting cracks.
【００１０】Ｍｎ：この合金は，鋳物の靱性確保のため
Ｆｅ含有量を低く設定しており，また比較的融点が高い
ため，金型に対して焼付きを生じ易い。Ｍｎは耐焼付き
性向上元素として寄与し，大型薄肉鋳物の高速充填鋳造
にとって不可欠の元素である。またＭｎは強度向上元素
でもある。ただし，Ｍｎ＜０．８ｗｔ％では合金の耐焼
付き性が低下し，一方，Ｍｎ＞１．５ｗｔ％では鋳物の
強度は向上するものの，その靱性が低下し，また溶湯の
流動性も悪化する。Mn: This alloy has a low Fe content in order to secure the toughness of the casting, and has a relatively high melting point, so seizure easily occurs on the die. Mn contributes as an element for improving seizure resistance and is an essential element for high-speed filling casting of large thin castings. Mn is also a strength improving element. However, when Mn <0.8 wt%, the seizure resistance of the alloy decreases, while when Mn> 1.5 wt%, the strength of the casting improves, but its toughness decreases and the fluidity of the molten metal deteriorates.
【００１１】Ｓｉ：Ｓｉは鋳物の強度向上に寄与する
が，Ｓｉ≧０．５ｗｔ％ではＭｇ2 Ｓｉ金属間化合物が
増加するため鋳物の靱性が低下する。Si: Si contributes to the improvement of the strength of the casting, but if Si ≧ 0.5 wt%, the toughness of the casting decreases because the amount of Mg 2 Si intermetallic compound increases.
【００１２】Ｆｅ：Ｆｅは鋳物の強度向上に寄与する
が，Ｆｅ≧０．５ｗｔ％ではＦｅ系晶出物が生成される
ため鋳物の靱性が低下する。Fe: Fe contributes to the improvement of the strength of the casting, but if Fe ≧ 0.5 wt%, the toughness of the casting decreases because Fe-based crystallized substances are produced.
【００１３】ＴｉおよびＺｒ：ＴｉおよびＺｒは，鋳物
の結晶粒の微細化による靱性の向上，鋳造割れの防止，
溶湯の流動性向上に寄与する。ただし，Ｔｉ＋Ｚｒ＜
０．３ｗｔ％では鋳物の靱性向上効果が不十分となる。
またＴｉ／Ｚｒ＜０．３およびＴｉ／Ｚｒ＞２では，そ
れぞれ鋳物の靱性が低下する。Ti and Zr: Ti and Zr improve the toughness by refining the crystal grains of the casting, prevent casting cracking,
It contributes to improve the fluidity of the molten metal. However, Ti + Zr <
If it is 0.3 wt%, the effect of improving the toughness of the casting becomes insufficient.
On the other hand, when Ti / Zr <0.3 and Ti / Zr> 2, the toughness of the casting decreases.
