Amorphous metals - amorphous metals

Japanese: 非晶質金属 - ひしょうしつきんぞく

Also known as amorphous metals. Metals that do not have long-range crystals in their atomic arrangement. Usually, solid metals are crystalline, but amorphous metals do not have a regular atomic arrangement. Since they are in a state similar to that of a liquid metal that has been cooled and solidified, they do not show anisotropy, are less susceptible to radiation damage, are stronger and more corrosion-resistant than normal metals, and some exhibit good properties as soft magnetic materials. They are made using methods such as liquid quenching, vacuum deposition, and electroplating. Full-scale development began around 1970, and amorphous alloys of metal-metal systems such as Cu-Zr and Ni-Nb, and metal-nonmetal systems such as Fe-B and Fe-P have been produced.

アモルファスamorphous金属とも。原子配列に，長範囲にわたる結晶をもたない金属。通常では，金属の固体は結晶になっているのに対して，非晶質金属では規則正しい原子配列が見られない。液体金属のまま冷却，固化したような状態なので，異方性を示さず，照射損傷も少なく，通常の金属より強靭(きょうじん)性，耐食性にすぐれ，軟磁性材料として良好な特性を示すものがある。液体急冷法，真空蒸着法，電気めっき法などでつくる。1970年ころから本格的な開発が進められ，Cu-Zr，Ni-Nbなどの金属‐金属系，およびFe-B，Fe-Pなどの金属‐非金属系のアモルファス合金が生み出されている。
