Definitions
- the present invention relates to a non-heat treatment type aluminum alloy and an aluminum alloy die-cast material using the aluminum alloy.
- the die-casting method can obtain a shape close to the final shape at the time of casting, as compared with the method of forming the member by applying plastic working to the wrought material, and the subsequent processing process.

- the cooling rate of the molten metal varies depending on the part of the member. Since the solid solution of Mg in the matrix has a high concentration in the portion where the cooling rate is high and a low concentration in the portion where the cooling rate is low, the difference in the amount of solid solution generated at this time causes a difference in mechanical properties depending on the site. It ends up.

Cr:0.01~1.00質量%、
Ca:0.001~0.050質量%、を含有し、
残部がAl及び不可避不純物よりなり、
前記不可避不純物の内、Mgの含有量が0.3質量%未満であること、
を特徴とするアルミニウム合金、を提供する。

本発明のアルミニウム合金は、Si:5.0~12.0質量%、Mn:0.3~1.9質量%、Cr:0.01~1.00質量%、Ca:0.001~0.050質量%、を含有し、残部がAl及び不可避不純物よりなっており、不可避不純物の内でもMgは0.3質量%未満となっている。以下、各成分について詳細に説明する。
Si:5.0~12.0質量%
Siは湯流れを良好にし、鋳造性を改善する働きを持つ。下限値に満たない場合は、鋳造性が十分でなくなり、上限値を超えて含有する際には、破壊の起点となる晶出物の形成により、伸びに悪影響をもたらすため、上記範囲で制限する必要がある。鋳造性と伸びをより良い水準で両立させるためには、Si:7.0~12.0質量%とすることが好ましく、Si:8.0~11.0質量%とすることがより好ましい。
Mnは鋳造時に溶湯が金型に焼付くことを防止するため、一定量含まれていなければならない。指定範囲の下限値に満たない場合は、その効果が十分でなく、上限値を超える場合にはAl-Mn系化合物の初晶が発生し、これが粗大な晶出物を形成すると、延性に悪影響を及ぼすため、上記範囲で制限されている。靭性と鋳造性の両立のためには、Mnの上限値を1.4質量%とすることが好ましく、1.0質量%とすることがより好ましく、0.8質量%とすることが最も好ましい。
Crはマトリクスに固溶することで、主に耐力を向上させる。下限値未満ではその効果が小さく、上限値を超えて添加した場合、耐力に関する悪影響は少ないものの、粗大なCr系晶出物を形成し、応力集中による破壊の起点となることで延性に悪影響を及ぼすため、上記範囲で制限する必要がある。固溶強化の効果をより確実に得るためには0.10質量%以上の添加が好ましい。なお、0.50質量%程度の添加で、粗大ではないもののCrを含む晶出物が出現するようになるため、本組成においてCrが固溶強化元素として耐力に寄与する限度は概ねこの値であると考えられる。これ以上の添加はコスト増加要因であることから、上限は0.50質量%とすることが好ましく、0.40質量%とすることがより好ましい。
Caは共晶Si組織を微細化することで、主に伸びに寄与する。下限値未満ではその効果が小さく、上限値を超えて添加しても、既に共晶Si組織が十分に微細化されていることから効果がない。また、過度に含有させると晶出物が粗大化し靭性に悪影響を及ぼす。加えて、Caの添加はコスト増加要因であることからも、上限については上記範囲で制限する必要がある。なお、Sr、Sb、Naを添加することでも共晶Si組織改良の効果を得ることができるが、本発明の組成においては、Caの場合よりやや伸びが劣る傾向にある。
Mg:0.3質量%未満
本発明のアルミニウム合金は、背景技術で述べたMgによる悪影響が、製品において望ましくない状況や場面での使用を想定している。従って、Mgは低い水準で規制する必要がある。上記悪影響をより確実に回避するには、Mg含有量を0.1質量%未満に制限することが好ましく、0.08質量%未満とすることがより好ましい。
一般的に、Feは鋳造時において溶湯が金型へ焼き付くことを防止する目的で添加されることが多い。これに対し、本発明のアルミニウム合金においては、Feの添加によりAl-Fe-Si系化合物、Fe-Si系化合物が形成され、延性に悪影響を及ぼす。従って、Feは0.4質量%以下、より好ましくは0.2質量%以下に規制することが好ましい。
