Abstract
Description
本出願では、「高マンガンオーステナイトの第3世代先進高張力鋼」と題し、2015年5月21日に提出された米国仮特許出願第62/164,643号の優先権を主張し、この参照によりその全体が本明細書に組み込まれる。
式1
本願の合金を次のように処理した。合金は典型的な実験方法に従い溶解し、鋳造した。合金の鋼の組成式を表1に示す。インゴットは熱間圧延前に1250℃の温度で熱した。インゴットは、最終温度を900℃とし、約8回で約3.3mmの厚さに熱間圧延した。ホットバンドをすぐに675℃に設定した加熱炉に入れ、続いて室温で約24時間冷却させ、コイル温度をシミュレートし、ホットバンドをコイル冷却させた。
