波纹状偏析是电渣重熔钢材的一种低倍缺陷,在钢材的横向酸侵试片上,由于抗腐蚀程度不同而呈现出一种花纹,尤其是当用过硫酸铵热溶液侵蚀后显示得更为清晰。最初发现时,观其外形,曾被误认为翻皮,后经研究证实,这种缺陷是由于区域性成份偏析形成组织差异所致,并非“翻皮”,故暂定名为“波纹状偏析”。 Corrugated segregation is a kind of low magnification defect of electroslag remelted steel, which shows a pattern due to the different degree of corrosion resistance in the transverse acid aggression test piece of steel, especially when it is eroded by ammonium persulfate hot solution More clear. Initially found, the appearance of its appearance, has been mistaken for the flap, after confirmed by the study, this defect is due to regional composition segregation caused by organizational differences, not “over the skin,” tentatively named “corrugated segregation ”.
