“…Some near-surface regions corresponding to areas of higher neutron attenuation coefficient were detected. We suggest that these are some patina areas [ 24 ]. These areas were virtually separated and cut from the total reconstructed volume of the battle axe to improve its model for future calculations.…”

A massive bronze battle axe from the Abashevo archaeological culture was studied using neutron tomography and manufacturing modeling from production molds. Detailed structural data were acquired to simulate and model possible injuries and wounds caused by this battle axe. We report the results of neutron tomography experiments on the bronze battle axe, as well as manufactured plastic and virtual models of the traumas obtained at different strike angles from this axe. The reconstructed 3D models of the battle axe, plastic imprint model, and real wound and trauma traces on the bones of the ancient peoples of the Abashevo archaeological culture were obtained. Skulls with traces of injuries originate from archaeological excavations of the Pepkino burial mound of the Abashevo culture in the Volga region. The reconstruction and identification of the injuries and type of weapon on the restored skulls were performed. The complementary use of 3D visualization methods allowed us to make some assumptions on the cause of death of the people of the Abashevo culture and possible intra-tribal conflict in this cultural society. The obtained structural and anthropological data can be used to develop new concepts and methods for the archaeology of conflict.

“…This allowed identification by an experienced numismatist of half of the coins scanned at the most. Scans have also been used to investigate the spatial distribution of remaining alloy and corrosion products (Bozzini et al 2014, Kichanov et al 2017, Abdurakhimov et al 2021) and optimize physical restoration (Bozzini et al 2014) or reveal the manufacture of coins (e.g. Abramson et al 2018;Herringer et al 2018;Salvemini et al 2018).…”

“…A practical development of this method is neutron tomography, in which a volumetric reconstruction of a three-dimensional model of the sample is performed from a set of individual radiographic projections [7]. The advantage of neutron radiography and tomography methods in the study of archaeological metal objects, in this case a bronze mirror, is the nature of the interaction of a neutron with a matter, which determines the deep penetration of neutrons into the thickness of massive objects, sensitivity to the distribution of hydrogen-containing compounds, sensitivity to differences in material density and chemical composition [8,9].…”

This work presents a study on the structure of a bronze mirror found in the Akterek burial complex by using neutron radiography and tomography. The manufacturing features and the physical state of this mirror was analyzed by three-dimensional model. It turned out that the rim on the edge was made of a different alloy, and the border between the rim and the base of the mirror is also visually visible. The morphological features and spatial distribution of pores and voids formed during secondary casting with the application of various patterns and ornaments have been studied in detail. The neutron tomography data made it possible to study the remains of a thin layer of corrosion on the surface of the mirror.
