Abstract:
The structural characteristics and phase composition of several ancient brass ingots obtained in the
archeological Shcherbet complex has been studied using neutron diffraction and tomography methods.
The XRF analysis and neutron diffraction provide high zinc content up to 30 wt.%. The neutron tomography yielded 3D data of the spatial distribution of chemical elements in the brass alloy of the studied
ingots, as well as inner voids and cavities as a possible result of the gas output during casting process.
The patina, as a cuprite phase, occupy volumes to 8 % of the volumes of the ingots.
