该数据集主要对首钢生产的460MPa级抗震耐蚀耐火钢中板进行600℃保温3h后的显微组织检测,将轧态的试样在箱式热处理炉保温3h后空冷,采用钨灯丝扫描电子显微镜进行组织观察后,可见针状铁素体宽化,粒状贝氏体转变为块状铁素体。
The data set is mainly for shougang production 460 mpa grade seismic corrosion resistant refractory steel plate for the microstructure after 600 ℃ heat preservation 3 h, the rolling state of sample in the chamber air cooling after heat treatment furnace insulation 3 h, the tungsten filament organization with scanning electron microscope observation, wide visible acicular ferrite, granular bainite into blocky ferrite.
