Purpose: The study compares the structure and properties titanium alloy Ti-6Al-4V produced by injection method allowing the production of massive amorphous materials in two varies – with and without suction. Design/methodology/approach: Samples were produced form titanium alloy Ti-6Al-4V produced by injection method. Structures and properties were compared of the same alloy but with different conditions in production process – with and without suction. To achieve the objective perused the following tests were carried out: study of phase composition by X-ray diffraction, observation of microstructure by using optical microscope and SEM, study of surface geometry – roughness, abrasion resistance tests and microhardness tests. Results: Microstructural studies have allowed to observe that the titanium alloy Ti-6Al-4V produced by injection method in both varies – with and without suction during injection to copper mold, has structure partially crystalized – nanocrystalline. In structure occur the crystal nuclei and lack of arrangement and regularity. The study of microhardness showed 100 HV 0.1 units higher hardness value in the embodiment with suction in comparison to the variant without suction. Titanium alloy Ti-6Al-4V produced with suction has better abrasion resistance in comparison with same alloy without suction. Alloy produced with suction has lower development area. Originality/value: The paper presented studies of massive amorphous and nanocrystalline alloys produced by alternative method – injection casting in two variants – with and without suction. That kind of production allow produced alloys with same chemical composition as commercial but with far better properties.
