Abstract The work discusses the corrosion behavior of a set of newly developed high strength and highly ductile multiphase steels consisting of various fractions of bainite, intercritical ferrite, retained austenite and pearlite from the composition 0.67 % C, 1.71 % Si, 0.86 % Mn and 96.69 % Fe (wt.%). The steels were made by various combinations of continuous cooling in the ferrite-pearlite zone followed by austempering. Multiphase interaction and rust constituents uniquely control the corrosion of the steels. At a particular isothermal temperature, initial increase in corrosion rate with increment of continuous cooling time is followed by decrease in corrosion rate once pearlite starts appearing.

贝氏体、临界铁素体、残余奥氏体和珠光体各相分数对多相钢腐蚀行为的影响

摘要 本文讨论了一组新开发的高强度和高韧性多相钢的腐蚀行为，该钢由不同比例的贝氏体、临界铁素体、残余奥氏体和珠光体组成，成分为 0.67% C、1.71% Si、0.86% Mn 和 96.69 % Fe (wt.%)。这些钢是通过在铁素体-珠光体区连续冷却和奥氏体回火的各种组合制成的。多相相互作用和锈成分独特地控制着钢的腐蚀。在特定的等温温度下，随着连续冷却时间的增加，腐蚀速率最初增加，一旦珠光体开始出现，腐蚀速率随之降低。
