Abstract: The paper presents the results of nondestructive studies of metal objects from the Chernaya Mogila (Black Grave) mound (10th century, Chernigov) from the collection of the State Historical Museum: a helmet, spearhead, sword fragment, and conglomerate of sintered weapons. In order to analyze the artifacts internal structure, assess their preservation, clarify the manufacturing technology and localize possible decorations, a complex of visualization methods was used. It includes X-ray computer tomography, synchrotron radiography, and tomography performed on the “KSRS-Kurchatov” synchrotron radiation source, and neutron tomography carried out at the IR-8 neutron source research reactor. The data obtained made it possible to reveal the design, ornamental, and technological features of the studied weapon items.
