Abstract

Abstract: Fe-Ni-based alloy can have both excellent soft magnetic properties and low Curie temperature. In this paper, 46 groups of Fe-Ni-based alloys are designed by Response Surface Methodology and prepared by arc melting and annealing, and their saturated magnetic polarization intensity ( J s ) and tensile strength ( R m ) are analyzed. The results show that J s and R m can be fitted with quartic and cubic models to predict the response values. The simultaneous addition of Ni and Cu to the Fe-based alloy has the greatest effect on the J s and R m . Fe-32Ni-2.7Cr-1.45Cu-1.5Si-2Mn alloy has a J s of 0.51 T, R m of 302.7 MPa, and T c of 70 °C, respectively, which can be a potential material for deicing. Importantly, all results show that the response surface methodology can be used to optimize and design multi-component alloy composition while reducing the number of experiments. Graphical Abstract: ga1 Highlights: Propose an RSM method for optimizing alloy composition and properties. 46 groups of Fe-Ni-based alloys were designed by RSM-BBD method. Established the regression models and equations between properties and composition. Disclosed the effects of two-factor composition on the magnetic and mechanical properties. Found a lower Curie point material of Fe-32Ni-2.7Cr-1.45Cu-1.5Si-2Mn.
