Electron tomography as a tool for studying the structures of amorphous alloys

Abstract

Structural defects in amorphous and nanocrystalline alloys of the CoP–CoNiP–NiP and CoW‒CoNiW–NiW systems are studied by means of electron tomography. An algorithm and software are developed to optimize the level of binarization of tomographic models used to select objects. Computer simulations show that the distribution of the volume of material density fluctuations is a Pareto distribution. It is established that a modified Pareto distribution describes the experimental distribution of volumes with a smaller error.
