![عکس صفحه اول مقاله: Evolution of modulated structure in Fe–Cr–Co alloy during isothermal ageing with different external magnetic field conditions Evolution of modulated structure in Fe–Cr–Co alloy during isothermal ageing with different external magnetic field conditions](/preview/png/1804988.png)
The evolution of modulated structure in Fe–Cr–Co alloy during isothermal ageing with and without external magnetic field was investigated by using transmission electron microscopy (TEM) and phase-field simulation. The isotropic modulated structure in Fe–Cr–Co alloy formed during isothermal ageing without external magnetic field could be converted to be anisotropy during further isothermal ageing under an 8 kOe external magnetic (thermo-magnetic treatment), and the formation of anisotropy was slower than the direct formation from spinodal decomposition under external magnetic field and is time dependent. The anisotropy characteristic of modulated structure in Fe–Cr–Co alloy subjected to thermo-magnetic treatment for 1 h remained during further isothermal ageing without external magnetic field for up to 20 h. Novel modulated structure could be obtained through specific thermo-magnetic treatment processes, which was confirmed by phase-field simulation.
