Among shape memory materials, iron based shape memory alloys are of special interest. Its relative low cost encourages mass scale production, such as concrete reinforcement. Metallurgical design of new compositions is abundant, and corrosion resistance must always be a concern. In the present work, the influence of cerium in the corrosion properties of a Fe-14Mn-4Si-9Cr-4Ni-xCe (x = 0.0, 0.18, 0.42, 0.96) was determined by anodic potentiodynamic polarization and EIS in simulated pore solution, with 0.6 M NaCl. Results revealed that cerium is responsible for an improvement in corrosion properties, although there is a threshold where this element begins to be detrimental.

在形状记忆材料中，铁基形状记忆合金特别受关注。其相对较低的成本鼓励大规模生产，例如混凝土加固。新成分的冶金设计非常丰富，并且必须始终关注耐腐蚀性。在目前的工作中，通过阳极电势极化和EIS在模拟孔溶液中确定了铈对Fe-14Mn-4Si-9Cr-4Ni-xCe（x = 0.0、0.18、0.42、0.96）腐蚀性能的影响，含0.6 M NaCl。结果表明，铈是腐蚀性能改善的原因，尽管有一个开始对该元素有害的阈值。
