Identification of Structure Ordering of Melt-Spun Fe_(70)Cr_(15)B_(15) Alloy by the Entropy Functionals

摘要

New techniques for the analysis of complex images were advanced by the example of a surface microrelief of the Fe_(70)Cr_(15)B_(15) alloys, obtained by the melt-spinning at different linear velocity of a quenching roller. Proposed techniques are based on the fast Fourier transform of the image using digital signal processors. The degree of morphological ordering/disordering of ribbons was determined due to the parameterization of mode spectra by entropy functionals. The best glass-forming ability for alloys of the studied composition was obtained at 30 m/s.
