To carry out calculations in the development of low-frequency hydroacoustic transducers, data on the physical and mechanical properties of structural materials, such as density, Young's modulus, Poisson's ratio, and ultimate strength, are required. For the manufacture of the emitting shell (body) of the transducer, specific material is used, obtained by the method of Selective Laser Melting (SLM). The material made by this technology often has parameters that differ significantly from the tabular data. The paper presents the results of studies of the physical and mechanical properties of the titanium alloy Ti-6Al-4V, obtained by the SLM-method. The studies were carried out by the method of elastic waves and destructive action. The research results are used for modeling and calculating the parameters of hydroacoustic emitter housings, manufactured using 3D printing from metal powders.
