摘要

摘要: 研究了不同压缩比2205双相不锈钢轧制复合板界面和复层的组织和性能。结果表明,压缩比为4和6的复合板复层均由奥氏体和铁素体组成,奥氏体和铁素体相界呈锯齿状;基层和复层界面处碳钢侧为单一铁素体,不锈钢侧可见一条不连续黑色条带;相比压缩比为4的复合板,压缩比为6的复合板复层铁素体含量更高,奥氏体γ相尺寸更小更长,耐腐蚀性更好,但强度无明显差异;基层和复层界面更平整,结合力更低。

Abstract: The microstructures and properties of the interface and lamination of 2205 dual-phase stainless steel rolled composite plate with different compression ratios are compared by metallographic microscope observation, chemical immersion and electrochemical corrosion test, Vickers hardness and shear strength test. It is found the composite plates with the compression ratios of 4 and 6 are composed of austenite and ferrite, and that the boundary between the austenite and ferrite is jagged. The carbon steel side at the interface between the base and cover metals is single ferrite, and a discontinuous black strip can be seen on the stainless steel side. Compared with the composite plate with the compression ratio of 4, the cover metal of the composite plate with the compression ratio of 6 has higher ferrite content, smaller and longer austenite γ phase, and better corrosion resistance. But there is no significant difference in strength. The interface between the base and cover metals is flatter and has lower binding force.
