Purpose: The study attempts to improve the properties of Ti15V3Al3Cr3Sn titanium alloy by applying an innovative method of shaping, injection with rapid cooling. The comparison of structures and properties of Ti15V3Al3Cr3Sn titanium alloy produced by two methods: conventional one by rolling and by injection with rapid cooling has been presented. Design/methodology/approach: Ti15V3Al3Cr3Sn titanium alloy produced by two methods: traditionally used rolling to achieve products in the form of sheets and unconventionally used injection of molten alloy to mold under pressure with rapid cooling. To achieve the objective the following studies have been carried out: observation of the microstructure by the optical and scanning electron microscope, EDS to verify the chemical composition, roughness measurement to examine surface layer geometry and microhardness tests. Findings: : Observations of microstructures have shown that the Ti15V3Al3Cr3Sn titanium alloy produced by overpressure with rapid cooling has the ability to create fine-grained structure in a top layer with a more ductile core. Such a combination of the structure has enabled to obtain better mechanical properties than the samples produced by the conventional method. Hard, durable and smooth surface layer with a ductile core provides the opportunity to use that material in many fields of materials engineering. Originality/value: The paper presents studies of titanium alloy shaped by the unconventional method of injection to achieve much better properties than for alloys obtained by rolling.
