Purpose: The paper presents a comparison of the structure and properties of titanium alloys Ti-6Al-4V produced by two methods: conventional and injection casting which allows obtaining solid amorphous alloys. Design/methodology/approach: Test samples are titanium alloys Ti-6Al-4V produced by two methods: conventional and injection casting. To achieve assumed objective the followed test were performed: phase composition by X-ray diffraction, microstructure observation was carried out, preformed to study the geometry of the surface – roughness and abrasion resistance measurements. Research limitations/implications: Observation of microstructures revealed that, titanium alloy Ti-6Al-4V produced by conventional method has a crystalline ordered structure which is typical for materials produced by continuous casting, while the titanium alloy produced by injection casting has a structure partially crystalline, and in most predominates amorphous structure which is characterized by a lack of order and regularity. Confirmation of structural studies were obtained diffraction records from qualitative X-ray analysis. Sample which was produced by continuous casting has higher rate of roughness than sample produced by injection casting. Titanium alloy produced by injection casting has higher rate of abrasion resistance than alloy produced by conventional casting. Higher roughness and higher abrasion resistance, these properties are beneficial for the process of fusion of the implant with the tissues in living organism, that same is desired in case when alloy will be used for biomedical applications. Originality/value: The paper presented study of solid amorphous alloys which were produced by injection casting. That kind of production allowed to achieve much better properties than for alloys produced by conventional method - continuous casting.
