Microstructure and Texture Evolution of Cold Drawn High Carbon Steel Wires before and after Annealing at High Temperature
摘 要
采用扫描电子显微镜(SEM)和电子背散射衍射技术(EBSD)作为分析手段, 对两种变形量SWRH82B冷拔高碳钢丝在奥氏体化高温退火处理前后的显微组织和织构变化进行了表征研究。结果表明: 该冷拔高碳钢丝显微组织中的珠光体经奥氏体化退火处理后由纤维状转变为等轴状; 冷拔高碳钢丝主要是〈110〉织构, 且织构强度随着变形量的增大而增强; 经奥氏体化退火处理后〈110〉织构强度明显下降, 且织构强度与变形量相关性减小, 同时还出现了〈112〉织构。
Abstract
Microstructure and texture change of SWRH82B cold drawn high carbon steel wires with different deformation degree before and after austenitic annealing treatment at high temperature were characterized and studied by means of scanning electron microscope (SEM) and electron back-scatter diffraction (EBSD). The results show that microstructure of the cold drawn high carbon steel wires changed from fibroid form into equiaxed form after austenitic annealing treatment. The texture of the cold drawn high carbon steel wires was mainly 〈110〉 and its intensity increased with the increase of the deformation amount. After austenitic annealing treatment, the intensity of 〈110〉 texture dropped distinctly, the relevance between texture intensity and deformation amount also reduced, and 〈112〉 texture appeared at the same time.
