加熱、電子ビーム加熱等がある。 Methods for melting include high frequency heating, resistance heating using a carbon or metal heating element, high frequency heating of a platinum or Ir metal crucible, infrared heating using a xenon lamp, etc., and electron beam heating.
そして希土類元素は酸化又は蒸発しやすいの
で、真空後アルゴン等の不活性ガス中大気圧又は
加圧して溶融する必要がある。 Since rare earth elements are easily oxidized or evaporated, it is necessary to melt them under vacuum and then under atmospheric pressure or pressurization in an inert gas such as argon.
これらの溶融合金は耐食性、耐熱性の良い白金

しながら噴出される。この調整を適当にすること
によつて、アモルフアス化の割合や、アモルフア
ス試料の厚さの調整ができる。 These molten alloys are ejected from platinum, Pr/Rh alloys, or Ir alloys, which have good corrosion resistance and heat resistance, while falling or under reduced pressure. By making this adjustment appropriately, the rate of amorphization and the thickness of the amorphous sample can be adjusted.
良質にアモルフアス希土類磁石を得るには、こ
の溶融合金を熱伝導性の良い回転体ドラムやロー
ル上の面に噴出させて急冷する必要がある。この
ために回転体はAl、Ag、Cu、Fe、等または合金
等の熱伝導性の良好な金属や合金が良い。 In order to obtain a high-quality amorphous rare earth magnet, it is necessary to spray this molten alloy onto the surface of a rotating drum or roll with good thermal conductivity and rapidly cool it. For this purpose, the rotating body is preferably made of a metal or alloy with good thermal conductivity such as Al, Ag, Cu, Fe, or an alloy.
しかし、耐熱性が必要な場合は耐熱性の良い
Mo、Ir、Ｗやこれらの合金製か又は回転体表面
に板として貼りつける必要がある。更に表面層を
ライニング加工すれば良好となる。 However, if heat resistance is required, use
It must be made of Mo, Ir, W, or an alloy thereof, or it must be attached as a plate to the surface of the rotating body. Further, if the surface layer is subjected to lining processing, it becomes better.
回転体は高速回転することによつて、冷却速度
を変化できるし又試料の厚さ、アモルフアス化の
割合に関係する。このため回転速度は1000rpm以
上が必要である。このようにして急冷することに
よつて10万℃／sec以上の冷却速度が得られ、大
部分アモルフアス化したリボン状の長い連続薄板
が得られる。 By rotating the rotating body at high speed, the cooling rate can be changed, and it is also related to the thickness of the sample and the rate of amorphization. Therefore, the rotation speed needs to be 1000 rpm or more. By rapidly cooling in this manner, a cooling rate of 100,000° C./sec or more can be obtained, and a long ribbon-like continuous thin plate that is mostly amorphous can be obtained.
また、回転体の直径も溶融合金の冷却時間との
関係があるため、50〜500φ程度は必要である。
良質なアモルフアス試料を得るには試料の厚さは
10〜100μ程度の場合であり100μ以上厚いとアモ
ルフアス化の割合が少なくなる。又、10μ以下だ
と連続して製造することが難しくなる。 Furthermore, since the diameter of the rotating body is also related to the cooling time of the molten alloy, it is necessary to have a diameter of about 50 to 500φ.
To obtain a good quality amorphous sample, the sample thickness must be
The thickness is about 10 to 100μ, and if it is thicker than 100μ, the rate of amorphous formation decreases. Moreover, if it is less than 10 μm, it will be difficult to manufacture it continuously.
このようにして製造されたアモルフアス希土類
磁石は多結晶体、スパツター、蒸着法等で製造さ
れたものより密度が100％であり、又急冷のため
成分の偏析がないこと、又結晶粒界がないことな
どから磁気特性のBrは高く、耐食性、靭性、強
度が良好となる。しかも短時間に連続して板状に
製造できることから、製造工数も少なくコスト的
にも安価となる。 The amorphous rare earth magnet produced in this way has a density 100% higher than that produced by polycrystalline, sputtering, vapor deposition, etc., and due to rapid cooling, there is no segregation of components, and there are no grain boundaries. For this reason, the magnetic properties of Br are high, and corrosion resistance, toughness, and strength are good. Furthermore, since the plate shape can be manufactured continuously in a short period of time, the number of manufacturing steps is small and the cost is also low.
また、このように急冷で得たアモルフアス試料
はリボン状、薄板状であり、曲げても折れ難い
し、硬さも非常に硬く、磁壁が動き難くなるため
に磁気特性のHcも大きくなる。 In addition, amorphous amorphous samples obtained by rapid cooling in this way are ribbon-like or thin-plate-like, and are difficult to break even when bent, and are extremely hard, making it difficult for the domain walls to move, resulting in a large magnetic property, Hc.
