time-temperature transformation curveとは 意味・読み方・使い方

While supersonic waves are applied to the Al alloy in which quasi-crystals are precipitately dispersed, or an the alloy or the Fe alloy having age-hardenability, aging treatment is performed at about a nose temperature of a TTT (time temperature transformation) curve.例文帳に追加

準結晶を析出分散させたＡｌ合金、時効硬化能を有するＡｌ合金、Ｆｅ合金などに超音波をあてながらＴＴＴ曲線のノーズ温度付近で時効処理する。 - 特許庁

A formed part composed essentially of amorphous alloy is heat treated under a reactive-gas-containing atmosphere and under the conditions of temperature and time within the amorphous region of the isothermal transformation curve (TTT curve) of the material, by which a ceramic hard layer is formed on the surface of the formed part.例文帳に追加

実質的に非晶質の合金からなる成形品を、反応性ガスを含む雰囲気下にてその材料の等温変態曲線（ＴＴＴ曲線）のアモルファス領域内の温度及び時間で熱処理し、上記成形品表面にセラミック系硬質層を形成する。 - 特許庁
