It was shown that the precipitates as an intermetallie compound of δ-(Fe,Ni,Co)Mo are responsible for strengthening in the steel. In case as-forged after aging, μ-phase appeared may reduce its toughness. After over-aging, e. g. 580℃ for 16h, a. c., some reverted austenite was formed. From observation in situ on heating the aged specimen in electron microscope up to 743℃, the δ grains were coalesced and the needle-like σ phase precipitated. Though the diffraction patterns of δ or σ phase can be commonly indexed, the difference of orientation between δ/α and σ/α seems to be more easily used to distinguish them in the maraging steel. 收稿日期: 1981-06-18      服务 把本文推荐给朋友 加入引用管理器 E-mail Alert RSS 作者相关文章 李斗星 叶恒强 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1981/V17/I6/625 [1] Magnee, A., Viatour, P., Drapier, J.
