The Effects of Modified Ausforming on Structure of Spring Steel
Transactions of Japan Society of Spring Engineers, 1989 鋼の有効な強靱化方策の1つとして改良オースフォーミングがある. 本報告では, ばね鋼の改良オースフォーミングについての基礎的知見を得るために加工フォーマスターを用いてシミュレーション実験を行い, 鋼の硬さ, ミクロ組織等におよぼす改良オースフォーミングの影響を調査した. また加工温度等の改良オースフォーム条件を変化させ, それが改良オースフォームの効果にどのような影響を与えるかを調査した. その結果を要約すると以下のようになる.(1) 改良オースフォームにより焼入れ硬さは上昇し, 焼入れ組織は微細化する.(2) SUP9Aの温度650℃でオースフォームしたものは加工による拡散変態促進のため不完全焼入れとなり硬さは著しく低下した.

Effect of Ausforming Temperature on the Microstructure of G91 Steel [PDF]
Metals, 2017 The development of thermomechanical treatments (TMT) has a high potential for improving creep-strength in 9Cr-1Mo ferritic/martensitic steel (ASTM T/P91) to operate at temperatures beyond 600 °C. To maximize the number of nanoscale MX precipitates, an ausforming procedure has been used to increase the number of nucleation sites for precipitation inside
