Abstract
Description
したがって、バルク凝固アモルファス合金に関する凝固前面の温度は、ガラス転移温度近傍とすることができ、その温度近傍で、この合金は、事実上、急冷アモルファスシート製品を引き抜く目的に関して、固体として作用する。
更には、BMG部品を成形するための溶融金属の冷却速度は、冷却の間の時間−温度プロファイルが、図2のTTT図内の結晶化領域を境界付けるノーズ形状領域を横断しないようなものでなければならない。図2では、Tノーズは、結晶化が最も急速であり、かつ最短の時間スケールで生じる、臨界結晶化温度Txである。
そのことは、加工処理温度が上昇するにつれて、軌跡内の水平な平坦部が遙かに短くなり得ることを単に意味する。

アモルファス又は非晶質固体
アモルファス合金又はアモルファス金属
それゆえ、この課題を克服するために、延性の結晶性金属の樹枝状の粒子又は繊維を含有する、金属ガラスマトリックスを有する、金属マトリックス複合材料を使用することができる。あるいは、深刻化を引き起こす傾向がある元素(例えば、Ni)が少ないBMGを使用することができる。例えば、Niを含まないBMGを使用することにより、そのBMGの延性を改善することができる。
