Abstract Advanced techniques of obtaining products require careful selection of materials for various industries. Titanium alloys are widely used in the aerospace, shipbuilding and mechanical engineering industries. The development of near-a titanium alloys should be considered a significant achievement in the field of metallurgy and heat treatment (HT) of titanium alloys. This article presents a study carried out with the aim of optimizing heat treatment modes for high-temperature titanium alloys obtained by direct laser deposition (DLD). Heat treatment was carried out in the temperature range (700-1000°C), covering three typical temperature ranges, i.e. the temperature range for the partial decomposition of martensite, the temperature range for the complete decomposition of martensite, and the phase transformation temperature were subsequently selected as the heat treatment temperatures. Based on metallographic analysis, the influence of heat treatment modes on the structure, as well as the tensile properties at room temperature, of TA15 titanium DLD-samples.

One of the disadvantages of using steel powders is the difficulty of producing such materials. In this article, steel powders from various manufacturers were discussed. The analysis of the surface, powder particles and the distribution of the fractional composition and the possibility of reuse was carried out. Direct laser deposition modes, using different laser power, were designed. From the obtained modes, tensile and impact bending samples were grown, and a comparative analysis of the obtained results was carried out.

Titanium Powders

Ti-6Al-4V powders from two different vendors and two different fraction were compared with respect to their microstructures, size-distributions, chemistries, surface appearances. In addition, the influence of these powders on the structure and properties of products manufactured by an additive direct laser deposition method were established. The main parameters that have a significant impact on the structure and properties of Ti-6Al-4V deposited parts were established.
