“…Particle size distribution also can affect the size factor of the structure, for example, the grain size. In the work of the authors present results [18] of powder size influence on the grain size for L-DED Ti-6Al-4 V titanium alloy (Figure 7).

The chapter presents the basic aspects of the use of metal powders in one of the main additive technologies—direct laser deposition (DLD). Direct laser deposition refers to a group of direct energy deposition (DED) methods and is analogous to Laser Metal Deposition (LMD) technology. The main requirements applied to DLD used metal powders are analyzed and substantiated. The influence of the basic properties of the powders on the quality of the deposited samples is demonstrated. An example of incoming quality control of powders, allowing its application in DLD technology, is presented. The results of experimental research on obtaining quality control samples for the most used metallic materials are presented. The results of structure and properties studies for the main groups of alloys based on iron, nickel, and titanium are shown. The potential for manufacturing products for various areas of industry using DLD has been demonstrated.

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.
