摘自《金属热处理》1983年第2期,郭新成: 本文是一篇综述文章,作者概述了钢中粒状贝氏体的组织结构、力学性能、形成机制和影响粒状贝氏体形成的因素等四部分。粒状贝氏体的组织结构比较复杂,特征是在较粗大的条块铁素体上分布有许多孤立的“小岛”。具有代表性的类型是较常见的组织一在块状铁素体上,无规律地分布着小岛,晶内晶界都有,且优先分布于原奥氏体晶界; Excerpt from the “metal heat treatment” 1983 the second period, Guo Xincheng: This article is a review article, the author outlines the structure of the granular bainite in steel, mechanical properties, formation mechanism and the factors affecting the formation of granular bainite and other four parts . The granular bainite structure is more complex, characterized by the distribution of coarser bar ferrite with many isolated “islands.” A representative type is the more common one in the organization of massive ferrite, irregular distribution of the island, the grain boundaries are, and preferentially distributed in the original austenite grain boundaries;
