摘    要：使用酸蚀法成功揭示了铝镇静钢中夹杂物的三维形貌和成分。酸蚀钢样品过程中,Al₂O₃夹杂物基本不与酸发生反应,只是样品基体与酸反应。短时间的酸蚀不会破坏夹杂物的成分。观察得到所研究的铝镇静钢中主要为粒径5~200μm的各种形貌的Al₂O₃夹杂物。本研究表明,酸蚀法是得到夹杂物三维形貌和成分的有效方法。

Abstract: The 3-dimensional morphology and composition of inclusions in a Al-killed steel were successfully revealed using the method of partial acid extraction.During partial acid extraction process,only the iron matrix reacted with the acid,and Al₂O₃ inclusions remained.Short time acid extraction did not change the composition of inclusions.The main inclusions in the current Al-killed steel were mainly 5-200 μm Al₂O₃-based inclusions with different morphology.The current work indicated that the partial acid extraction is an efficient method to achieve the 3-dimensional morphology and composition of inclusions in steel.
