The granular bainite stands out in surface relief during its transformation Its ferrite grows up longitudinally and form parallel laths The K-S orientation relationship is kept between ferrite and austenite The morphology of its islands appears as the shape of short lath and with a tendency of being parallelly distributed in the bainite-ferrite matrix. The granular structure does not stand out in surface relief in the formation of equiaxial ferrite. It's ferrite can grow across the grain boundary of parent phase, and has no strict orientation relationship with parent phase The shape of the islands is irregular, and its arrangement on the matrix is also irregular. The grain boundary of austenite couldn't be revealed clearly Except the difference of the transformation temperature, the granular structure possessed Widmanstatten ferrite is similar to the granular bainite in characteristics. Finally, the models of the growth of granular bainite and granular structure are suggested. 收稿日期: 1986-04-18      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 方鸿生 白秉哲 郑秀华 郑燕康 陈秀云 赵如发 44.8K 链接本文: https://www.ams.org.cn/CN/      或      https://www.ams.org.cn/CN/Y1986/V22/I4/5 1 Habraken, L.J., Rev.
