Abstract
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.
