The porous molded body is impregnated with lithium by immersing the molded body in a lithium molten bath in an inert gas atmosphere or hydrogen atmosphere, and then the magnesium-lithium composite is heated to a temperature below the melting point of the alloy. A magnesium-lithium alloy molded body is formed by heating and alloying at a temperature of .
本発明は軽量で比強度の大きいマグネシウム・リチウム
合金成形体の製造方法に関する。The present invention relates to a method for manufacturing a magnesium-lithium alloy compact that is lightweight and has high specific strength.
マグネシウム・リチウム（以下Ｍｇ−Ｌｉ）合金は実用
金属材料の中で最も軽量で比強度が大きいため航空機器
に限らず電子機器においても軽量を必要とする用途に使
用されている。Magnesium-lithium (hereinafter referred to as Mg-Li) alloy is the lightest among practical metal materials and has the highest specific strength, so it is used not only in aircraft equipment but also in electronic equipment that requires light weight.
この用途は例えば磁気ディスクにおいて磁気ヘッドを支
えるヘッドアームや高速プリンタのキャリーなどである
。This application is, for example, a head arm that supports a magnetic head in a magnetic disk, a carry for a high-speed printer, etc.
なお、比強度とはその材料の単位重量あたりの引張り強
度を云う。Note that specific strength refers to the tensile strength per unit weight of the material.
ここで、比強度はＭｇとＬｉとの組成比により異なるの
で、用途に応じて正しい組成比の合金を作ることが必要
である。Here, since the specific strength varies depending on the composition ratio of Mg and Li, it is necessary to make an alloy with the correct composition ratio depending on the application.
Ｍｇ−Ｌｉ合金め製法としては従来より鋳造法が用いら
れている。Casting has been conventionally used as a manufacturing method for Mg-Li alloys.
然し、Ｍｇの融点が６５０℃、Ｌｉの融点は１８０℃と
大きく離れており、またＬｉは極めて活性な金属であり
、蒸発し易いため鋳造法により目的の組成比の合金を精
度よく形成することが難しい。However, the melting point of Mg is 650°C and the melting point of Li is 180°C, which are significantly different from each other, and Li is an extremely active metal that evaporates easily, so it is difficult to accurately form an alloy with the desired composition ratio using a casting method. is difficult.
Ｍｇ−Ｌｉ合金は実用金属材料の中で最も軽量で比強度
の高い材料であるため一般に用いられているが、必要と
する組成比のものを安定に製造できないことが問題であ
る。Mg-Li alloys are commonly used because they are the lightest and have the highest specific strength among practical metal materials, but the problem is that they cannot be stably manufactured with the required composition ratio.
上記の問題はＭｇ粉末をプレス成形して多孔質の成形体
を作り、該成形体を不活性ガス又は水素（Ｈｚ）ガス雰
囲気中のＬｉ溶融浴に浸漬して前記多孔質成形体の中に
Ｌｉを含浸させた後、該Ｍｇ−Ｌｉ複合体を該合金の融
点以下の温度で加熱し、合金化するＭｇ−Ｌｉ合金成形
体の製造方法により解決することができる。The above problem can be solved by press-molding Mg powder to make a porous molded body, immersing the molded body in a Li molten bath in an inert gas or hydrogen (Hz) gas atmosphere, and then inserting the molded body into the porous molded body. The problem can be solved by a method for manufacturing an Mg-Li alloy molded body, in which the Mg-Li composite is impregnated with Li and then alloyed by heating the Mg-Li composite at a temperature below the melting point of the alloy.
従来の鋳造法によってＭｇ−Ｌｉ合金を製造する場合に
所定の組成比の合金ができにくい理由は液相一液相反応
を用いるからである。The reason why it is difficult to produce an alloy with a predetermined composition ratio when manufacturing a Mg-Li alloy by the conventional casting method is because a liquid phase-liquid phase reaction is used.
すなわち、Ｍｇの融点が６５０℃、Ｌｉの融点が１８０
℃と離れ過ぎているのに加えてＬｉが活性であることが
らＬｉに非常に蒸発し易くなっているためである。That is, the melting point of Mg is 650°C, and the melting point of Li is 180°C.
This is because the temperature is too far away from the temperature and Li is active, making it very easy to evaporate into Li.
そこで、本発明は固相一液相反応と固相−固相反応を組

望の組成比の合金を得るものである。Therefore, the present invention combines a solid phase-liquid phase reaction and a solid phase-solid phase reaction to obtain an alloy having a desired composition ratio by performing alloying under a reasonable condition.
