序言 钢中共存碳化物的分离鉴定是钢强化机理研究不可缺少的方法之一。在一般中低合金钢中,常见的碳化物有合金渗碳体M_3C、M_6C、M_2C、MC、M_7C_3和M_(23)C_6。要了解这些碳化物的生成规律、存在量、冶炼条件、热处理制度和机械性能之间的关系,就要求有一个有效的碳化物分离鉴定的好方法。 从钢中把所生成的所有碳化物定量地提取出来目前国内外工作开展较成熟。有电解 Preface The separation and identification of coexisting carbides in steel is one of the indispensable methods for the study of strengthening mechanism of steel. In general low alloy steel, the common carbides are cementite M_3C, M_6C, M_2C, MC, M_7C_3 and M_ (23) C_6. Understanding the formation, abundance, smelting conditions, heat treatment regimes, and mechanical properties of these carbides requires an effective method of separating and identifying carbides. All the carbides generated from steel were quantitatively extracted at home and abroad to carry out more mature work. Electrolysis
