| 摘 要： | 通过扫描电镜、能谱仪、显微硬度计和拉伸实验研究了退火工艺对热镀锌用冷轧低碳高强钢组织及性能的影响。结果表明,在600℃退火时,组织处于回复阶段,几乎没有再结晶;625℃保温5 min退火后,再结晶基本完成,组织中有大量渗碳体颗粒弥散析出,并且随着退火温度升高或保温时间延长渗碳体沿铁素体晶界聚集粗化;在625℃保温10 min退火后,再结晶已经完成并且发生长大现象,组织为等轴状铁素体+渗碳体颗粒,晶粒尺寸约为5.01μm;650、675、700℃保温10 min退火后,铁素体晶粒进一步长大;随着退火温度升高和保温时间延长,屈服强度和抗拉强度降低,伸长率升高。625℃×5 min退火可以获得优良的综合力学性能。
