Improvement of Processes for Obtaining Titanium Alloys for Manufacturing Parts with Design Elements

Abstract

The article presents a systematic block diagram for manufacturing TiAl titanium alloys. Based on the developed block diagram of TiAl components, the main already known stages of powder metallurgy manufacturing technology were improved. Based on the obtained chemical reaction of structurally inhomogeneous materials, the intermetallic phase relationship of titanium aluminides was revealed. It is studied that in the zone of interaction of the composition of titanium and aluminium components, a certain thickness of the transition layer is formed, which practically does not change with increasing exposure time. The crystallization process of inhomogeneous TiAl materials was studied in more detail using the constructed crystal lattice of titanium alloys. As a result, the formation of an atomic grid in space was observed. It should also be noted that the recognition of individual areas in microstructural images was carried out using the Smart-eye software package. The microscopic analysis allowed us to predict the main structural characteristics of TiAl components. In particular, to carry out more detailed control of the particles of TiAl components, their density, porosity, relationships with each other, the shape and size of TI and Al powders. The structure of the interaction of TiAl materials and the interpolation dependence of the formed intermetallic layer are also presented. Based on the conducted research, the quality indicators of parts with structural elements, particularly gears, have been improved.
