Purpose: In these paper was were characterized mechanical properties of titanium alloy Ti-6Al-4V, which were produced by two methods - conventional casting and injection casting. Studies were presented by comparing of samples which were produced by these methods. Design/methodology/approach: Samples were produced by two methods – conventional and injection casting. To achieve the objective were performer the following steps: the microstructure was carried out, the analysis of mechanical properties was done (microhardness), study of surface roughness was made, research of abrasion was made and phase composition by X-ray diffraction was made. After then then a comparison of these studies between these samples was made. Findings: The study of the microstructure was observed that the titanium alloy Ti-6Al-4V prepared by the conventional method, it has equiaxed and globular structure. In contrast, titanium alloy produced by the injection has strips structure, where phase α’ is on phase β border. Further studies have shown that a sample of titanium alloy Ti-6Al-4V produced by injection it has a much greater tribological resistance because it has a higher microhardness and much greater roughness than the sample of the same alloy produced by the conventional method. Originality/value: In this article conducted a comparative characteristics for the two production methods - conventional and injection - titanium alloy Ti-6Al-4V. The research indicated that much better mechanical properties are characterized alloys produced by injection.
