本発明は熱伝導性に優れたダイカスト鋳造用高熱伝導性マグネシウム合金に関し、より詳しくは、ヒートシンク等の高熱伝導性を必要とする製品をダイカスト鋳造するのに好適なダイカスト鋳造用高熱伝導性マグネシウム合金に関する。 The present invention relates to a high thermal conductivity magnesium alloy for die casting that has excellent thermal conductivity. More specifically, the present invention relates to a high thermal conductivity magnesium alloy for die casting that is suitable for die casting a product that requires high thermal conductivity such as a heat sink. About.
マグネシウム合金のダイカスト鋳造品は種々の用途に広く用いられている。しかしながら、マグネシウム合金は、用途によっては強度や耐熱性、熱伝導性等が充分ではない。純マグネシウムの熱伝導率が１６７Ｗ／ｍ・Ｋであるのに対して、例えば、一般的なダイカスト鋳造用マグネシウム合金であるＡＺ９１の熱伝導率は９０Ｗ／ｍ・Ｋ未満である。このように熱伝導率が低下する原因はマグネシウム固溶体中にアルミニウム等の熱伝導性を悪くする元素が固溶されていることである。マグネシウム合金のダイカスト鋳造品を高温の使用環境で用いられる部材や使用中に発熱したりする部材に用いると、放熱が良好に行われず、部材に熱変形が生じることがあり、マグネシウム合金のダイカスト鋳造品をヒートシンク等に用いることは不適切である。 Magnesium alloy die castings are widely used in various applications. However, the magnesium alloy is not sufficient in strength, heat resistance, thermal conductivity, etc. depending on the application. While the thermal conductivity of pure magnesium is 167 W / m · K, for example, the thermal conductivity of AZ91, which is a general die casting magnesium alloy, is less than 90 W / m · K. The reason why the thermal conductivity is lowered in this manner is that an element that deteriorates the thermal conductivity such as aluminum is dissolved in the magnesium solid solution. When a magnesium alloy die cast product is used for a member used in a high temperature use environment or a member that generates heat during use, heat radiation may not be performed satisfactorily and the member may be thermally deformed. It is inappropriate to use the product as a heat sink.
それで、ヒートシンクの製造に用いるのに適した種々の組成のアルミニウム合金が提案されている（例えば、特許文献１〜６参照。）。しかしながら、マグネシウム合金はアルミニウム合金よりもさらに軽量であり、軽量化の観点からヒートシンク等の製造に高熱伝導性マグネシウム合金を用いることが望まれていた。 Therefore, aluminum alloys having various compositions suitable for use in manufacturing a heat sink have been proposed (see, for example, Patent Documents 1 to 6). However, a magnesium alloy is lighter than an aluminum alloy, and it has been desired to use a highly heat-conductive magnesium alloy for manufacturing a heat sink and the like from the viewpoint of weight reduction.
高熱伝導性である鋳造用マグネシウム合金として、亜鉛を８〜１２質量％含有するマグネシウム合金（例えば、特許文献７参照。）、熱伝導率が高い銅及びカルシウムを含有するマグネシウム合金（例えば、特許文献８〜１０参照。）、アルミニウムとカルシウムとを組成比（Ｃａ／Ａｌ）０．５〜１．５で含有するマグネシウム合金（例えば、特許文献１１）等が提案されている。 As a magnesium alloy for casting having high thermal conductivity, a magnesium alloy containing 8 to 12% by mass of zinc (see, for example, Patent Document 7), a magnesium alloy containing copper and calcium having high thermal conductivity (for example, Patent Document) 8-10), magnesium alloys containing aluminum and calcium in a composition ratio (Ca / Al) of 0.5 to 1.5 (for example, Patent Document 11) have been proposed.
本発明もまた熱伝導性に優れたダイカスト鋳造用高熱伝導性マグネシウム合金を提供することを目的としている。 Another object of the present invention is to provide a high thermal conductive magnesium alloy for die casting that has excellent thermal conductivity.
本発明者らは、マグネシウム合金の鋳造性を維持するために少量のアルミニウム及び／又は亜鉛を含有させるが、アルミニウム及び／又は亜鉛を含有するマグネシウム固溶体を純マグネシウムの状態にできるだけ近づけて熱伝導率の低下を防止し、析出物による析出強化で合金強度を維持することについて鋭意検討した。その結果、マグネシウム合金に少量のランタノイドを含有させることにより、熱伝導性に優れたダイカスト鋳造用高熱伝導性マグネシウム合金が得られることを見出し、本発明を完成した。 In order to maintain the castability of the magnesium alloy, the present inventors include a small amount of aluminum and / or zinc. However, the magnesium solid solution containing aluminum and / or zinc is brought as close to the state of pure magnesium as possible so that the thermal conductivity. In order to prevent the decrease in the strength of the alloy and to maintain the strength of the alloy by precipitation strengthening with precipitates, the inventors have intensively studied. As a result, it was found that a high heat conductive magnesium alloy for die casting excellent in thermal conductivity can be obtained by adding a small amount of lanthanoid to the magnesium alloy, and the present invention has been completed.

That is, the high thermal conductive magnesium alloy for die casting of the present invention is (1) 1.5 to 3% by mass of a lanthanoid,
(2) one or both of 0.5 to 1.5% by weight of aluminum and zinc and (3) one or both of 0.2 to 0.6% by weight of manganese and zirconium, with the balance being magnesium and It consists of inevitable impurities.

また、本発明のダイカスト鋳造用高熱伝導性マグネシウム合金は１．５〜３質量％のランタン、０．５〜１．５質量％の亜鉛、及び０．４〜０．６質量％のジルコニウムを含有し、残部がマグネシウム及び不可避不純物からなることを特徴とする。 The high heat conductive magnesium alloy for die casting of the present invention contains 1.5 to 3% by mass of lanthanum, 0.5 to 1.5% by mass of zinc, and 0.4 to 0.6% by mass of zirconium. And the balance consists of magnesium and inevitable impurities.
本発明のダイカスト鋳造用高熱伝導性マグネシウム合金はダイカスト鋳造が可能であり、熱伝導性に優れているので、ヒートシンク等の高熱伝導性を必要とする製品をダイカスト鋳造するのに好適に用いることができる。 Since the high heat conductive magnesium alloy for die casting of the present invention can be die cast and has excellent thermal conductivity, it can be suitably used for die casting a product that requires high thermal conductivity such as a heat sink. it can.
本発明のダイカスト鋳造用高熱伝導性マグネシウム合金は
（１）１．５〜３質量％のランタノイド、
（２）０．５〜１．５質量％のアルミニウム及び亜鉛の一方又は両方、及び
（３）０．２〜０．６質量％のマンガン及びジルコニウムの一方又は両方
を含有し、残部がマグネシウム及び不可避不純物からなるものである。
The highly heat-conductive magnesium alloy for die casting of the present invention comprises (1) 1.5 to 3% by mass of a lanthanoid,
(2) one or both of 0.5 to 1.5% by weight of aluminum and zinc and (3) one or both of 0.2 to 0.6% by weight of manganese and zirconium, with the balance being magnesium and It consists of inevitable impurities.
本発明のダイカスト鋳造用高熱伝導性マグネシウム合金においては、ランタノイド（例えば、ランタン、セリウム）とアルミニウム及び亜鉛の一方又は両方とを含有するので、それらは金属間化合物を形成し、純マグネシウムに近い相の周りにその金属間化合物が点在し、その結果としてマグネシウム合金の熱伝導性が良好になる。ランタノイドの含有量が１．５質量％未満の場合には、熱伝導性が不十分となる傾向があるが、ランタノイドの含有量が３質量％を超えても、それに見合った効果は得られない。 In the high heat conductive magnesium alloy for die casting of the present invention, since it contains a lanthanoid (for example, lanthanum, cerium) and one or both of aluminum and zinc, they form an intermetallic compound and are close to pure magnesium. Are interspersed with the intermetallic compound, and as a result, the thermal conductivity of the magnesium alloy is improved. When the lanthanoid content is less than 1.5% by mass, the thermal conductivity tends to be insufficient, but even if the lanthanoid content exceeds 3% by mass, an effect commensurate with it cannot be obtained. .
本発明のダイカスト鋳造用高熱伝導性マグネシウム合金においては、アルミニウム及び亜鉛の一方又は両方を合計で０．５〜１．５質量％含有する。アルミニウム及び亜鉛の一方又は両方を合計で０．５質量以上含有することにより、マグネシウム合金の溶融温度が低下し、ダイカスト鋳造が容易になる。しかし、アルミニウム及び亜鉛の一方又は両方を合計で１．５質量を超えて含有していると、上記のように金属間化合物を形成するとしても、熱伝導性が低下する傾向がある。 In the high heat conductive magnesium alloy for die casting of the present invention, one or both of aluminum and zinc are contained in a total amount of 0.5 to 1.5% by mass. By containing one or both of aluminum and zinc in a total amount of 0.5 mass or more, the melting temperature of the magnesium alloy is lowered, and die casting becomes easy. However, if one or both of aluminum and zinc exceeds 1.5 mass in total, the thermal conductivity tends to decrease even if an intermetallic compound is formed as described above.

The effect of crystal grain refinement can be obtained by containing one or both of manganese and zirconium in a total amount of 0.2% by mass or more, but even if one or both of manganese and zirconium exceed 0.6% by mass in total , You can not get the appropriate effect.
本発明のダイカスト鋳造用高熱伝導性マグネシウム合金においては、１．５〜３質量％のランタン、０．５〜１．５質量％のアルミニウム、及び０．２〜０．６質量％のマンガンを含有し、残部がマグネシウム及び不可避不純物からなることが好ましい。この場合にはマンガンは不純物除去剤としても機能する。 The high heat conductive magnesium alloy for die casting of the present invention contains 1.5 to 3% by mass of lanthanum, 0.5 to 1.5% by mass of aluminum, and 0.2 to 0.6% by mass of manganese.
