The granular bainite with non-directional islands formed in the hightemperature range of bainitic transformation, the granular bainite with directional islands formedin the medium temperature range. The bainite which formed in the lower temperature range istypically featherlike. But it was found that the carbon-rich austenite islands, Present betweenferrite laths, transformed to martensite on cooling. Acicular lower bainite was not observed inthe steels. Key words： Mn-Nb-V steel    bainitic transformation    granular bainite    featherlike bainite 收稿日期: 1988-02-18      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 曹仁焕 马洪悌 阎振棨 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1988/V24/I2/135 1 大森靖也,大谷泰夫,邦武立郎.铁钢,1971;57:1690 2 Habraken L.
