The structure, mechanical properties and impact strength of 5-layered composites based on maraging and low-alloy mild steels are investigated. The effect of subsequent heat treatment on the microstructure and mechanical properties of layered composites is studied. The contribution of the presence of the initial ultrafine-grained microstructure of maraging steel to the formation of the mechanical properties of explosion-welded and thermally strengthened layered composites is evaluated.

The specificity of paleoanthropological researchs and accurate anthropological documentation is due to the complexity of the form of anthropological objects, their uniqueness, high historical and scientific value. The main purpose of this work is to develop methods for creating 3D models with a high degree of informatively for the development of digital documentation systems of paleoanthropological objects. The article presents a comparative analysis of digital models of anthropological object create using photogrammetry and computed tomography. It is shown that the combined use of non-contact methods of photogrammetry and computed tomography allows to create high-precision three-dimensional models with photorealistic texture and accurate internal and hidden geometry. The proposed approach allows not only to create virtual collections for wide sharing of specialists, but also using modern methods of additive manufacturing to make exact copies of unique artifacts.

Paleo-anthropological research has its specificity closely related with studied objects. Their complicated shape arises from anatomical features of human skull and other skeletal bones. The degree of preservation is associated with the fragility of palaeo-anthropological material which usually has high historical and scientific value. The circumstances mentioned above enhance the relevance of photogrammetry implementation in anthropological studies. Thus, such combination of scientific methodologies with up-to-date technology creates a potential for improvement of various stages of palaeo-anthropological studies. This can be referred to accurate documenting of anthropological material and creation of databases accessible for wide range of users, predominantly research scientists and students; preservation of highly valuable samples and possibility of sharing information as 3D images or printed copies, improving co-operation of scientists world-wide; potential for replication of contact anthropometric studies on 3D images or printed copies providing for development of new biometric methods, and etc. This paper presents an approach based on photogrammetric techniques and non-contact measurements, providing technological and methodological development of paleo-anthropological studies, including data capturing, processing and representing.
