摘要
本研究探讨了退火温度和时间对商业级低碳钢晶粒分布和纹理发展的影响,这些钢经过冷轧,随后在 700 或 800 °C 下分别进行 5 分钟和 10 分钟的电炉退火。对退火样品进行的扫描电子显微镜和电子反向散射衍射分析表明,铁素体晶界上存在雪明碳铁的等轴微观结构。在 700 °C 下退火 5 分钟和 10 分钟的样品呈现出双峰晶粒分布,而在 800 °C 下则形成了较大的铁素体晶粒。在 700 °C 下退火 5 分钟的样品的取向分布函数纹理表现为γ纤维纹理 ND//〈1 1 1〉和立方体纹理 ND//〈0 0 1〉。提高退火温度和时间可降低立方体纹理的强度,增强γ纤维,使拉伸伸长率从 8% 提高到 38%。
The impact of annealing temperature and time on the grain distribution and texture evolution of cold-rolled electric-furnace annealed low-carbon steel
This study investigated the effect of annealing temperature and time on the grain distribution and textural development of commercial-grade low-carbon steel that undergone cold rolling and subsequent electric-furnace annealing at either 700 or 800 °C for 5 and 10 min. Scanning electron microscopy and electron backscatter diffraction analyses of the annealed samples revealed equiaxed microstructures with cementite at the ferrite grain boundaries. The samples annealed at 700 °C for 5 and 10 min exhibited a bimodal grain distribution, while larger ferrite grains formed at 800 °C. The orientation distribution function texture of the sample annealed at 700 °C for 5 min exhibited both a γ-fiber ND//〈1 1 1〉 and a cube texture ND//〈0 0 1〉 . Raising the annealing temperature and time reduced the intensity of cube texture and strengthened the γ-fiber, increasing tensile elongation from 8 to 38 %.
