药皮合金元素对fv520(b)钢焊缝组织和韧性的影响
Keywords: 金属材料,药皮,合金元素,fv520(b)钢,组织,冲击韧性
Abstract:
？在焊条药皮中添加中碳锰铁和镍粉将mn、ni元素过渡到fv520(b)钢焊缝,用金相分析、冲击试验、xrd分析和sem观测等手段研究了药皮合金元素对fv520(b)钢焊缝的组织和韧性的影响。结果表明:fv520(b)钢焊缝组织以回火索氏体和板条马氏体为主,出现残余奥氏体和二次析出相;随着合金元素的增加,焊缝的组织更加细小致密,马氏体片层更加均匀细小,分布更加弥散。与酸性药皮相比,碱性药皮过渡合金元素的效果更显著,因此焊缝的冲击韧性更优良。用药皮过渡mn、ni能提高焊缝中奥氏体的含量,进而改善fv520(b)钢焊缝的冲击韧性。与mn相比,添加ni提高焊缝韧性的效果更为显著。
