20 Mar 2019: 钢中的贝氏体. 作者：H. K. D. H. Bhadeshia. 译者：哈尔滨工业大学，甄良. Bainite in Steels, by H. K. D. H. Bhadeshia. Translated by: Zhengliang, Harbin Institute of Technology. 引言. 在典型的钢的时间-温度转变（TTT）图中存在一个较宽的中间温度范围，在这个温度范围内既不形成珠光体也不形成马氏体，而是形成细铁素体条（或板条）与渗碳体颗粒的集合体。这些中间组织通常称为贝氏体。这种组织是Davenport and Edgar Bain在研究奥氏体的等温分解时发现的。在athermal处理过程中，当冷速对珠光体形成来说太快、而对形成马氏体来说又太慢时会发生贝氏体转变。随转变温度的下降，贝氏体的性质发生变化。可以分成两类：上贝氏体和下贝氏体。. 上贝氏体. 下贝氏体. 形状变化. 贝氏体中的碳. 动力学. 转变过程. 粒状贝氏体. 回火. 合金元素. 应用. 主要参考文献. 图库. 本站点评述. 上贝氏体. 上贝氏体的显微组织中有细铁素体片，每一铁素体片厚约0.2 m m、长约10 m
