The atomic structure of amorphous (FeCoNi)70Ti10B20 alloy synthesized by mechanical alloying was in-vestigated using high energy synchrotron X-ray diffraction and inverse Monte Carlo simulations of pair distribution functions. Empirical potential structure refinement indicates a chemical short-range order at the length scales of 2.1-2.5 & ANGS; via local atomic arrangements forming deformed bcc-like clusters. The structural model obtained was described by bond lengths, coordination numbers, and bond angle dis-tribution functions determined for the first neighbor atoms by x-ray scattering supplemented with 3D Monte Carlo simulations. & COPY; 2023 Elsevier B.V.
