1) nitrogenous bubble
氮气泡
1.
Based on the microanalysis, it is found that the nitrogenous bubbles distribute along grain boundaries of columnar dendrites, and the slab cracking may be due to too high N content in the steel.
使用扫描电镜和电子探针能谱仪分析了304不锈钢热轧龟裂样品,给出了开裂的显微特征,并认为由于氮含量较高,板坯在热轧时柱状晶晶界析出氮气泡,从而导致板坯沿晶开裂。

补充资料：表面气泡
表面气泡
skin hole
b iaomian qiPao表面气泡(skin hole)钢锭表面上一些开口的孔眼。是钢中气体析出于钢锭表皮而形成的;钢锭模壁潮湿，或使用的保护渣潮湿，在浇注时蒸发出气体，也会使钢锭形成表面气泡。它会使轧材出现深口、裂痕、甚至海绵面等缺陷。其防止措施主要是降低钢液气体含量，保持锭模和保护渣干操。 (汪建农)
