在实验室设计了5种V-N微合金中碳钢,研究微合金元素含量对钢的组织和性能的影响,并用透射电镜分析了析出相的结构、成分、尺寸分布和形貌,讨论了中碳微合金钢的沉淀强化机制。
Five kinds of VN microalloyed medium carbon steels were designed in the laboratory to study the effect of microalloy content on the microstructure and properties of the steel. The structure, composition, size distribution and morphology of the precipitated phase were analyzed by transmission electron microscopy. Microalloyed steel precipitation hardening mechanism.
