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      Received:  18 February 1988      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/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.
