PT Journal AU Horky, R Kusmierczak, S Vlach, T TI Influence of Selected Heat Treatment on Alloy Properties of Ti-6Al-4V Alloy SO Manufacturing Technology Journal PY 2025 BP 482 EP 488 VL 25 IS 4 DI 10.21062/mft.2025.054 DE Titanium alloy; Heat treatment; Yield strength; Surface; Microstructure; Fractography; Fracture surface AB Titanium is the polymorphic metal whose recrystallization temperature significantly affects its final properties. The area between 850 °C and 995 °C is a very important area from the point of view of heat treatment of titanium alloys. It is a transition area just below the β transition limit. This article deals with the analysis of the influence of thermal loading on the change in tensile strength and fracture behavior of titanium alloys in comparison with thermally unloaded samples. Monitoring of fracture surfaces and description of the internal structure of the material. ER
