Purpose of this paper was to investigate the phenomenon of microstructural banding in three titanium alloys: Ti-6Al-4V, Ti-10V-2Fe-3Al and Ti-3Al-8V-6Cr-4Mo-4Zr. Design/methodology/approach: The microstructure of the investigated materials in as-delivered condition was characterized. Compression tests were performed on Gleeble thermomechanical simulator to investigate banding phenomena occurring in the microstructure of each studied alloy. Moreover, banding phenomena was also investigated in the case of forging obtained from Ti-6Al-4V alloy. Heat treatment conditions allowing to reduce banding in the microstructure of the investigated alloys were also determined. Findings: Thermomechanical processing leading to dynamic recrystallization in the investigated alloys restricts the formation of bands in their microstructure. Homogenizing treatment can also reduce banding in such alloys. Research limitations/implications: Future research should concern the investigations of grain size in the recrystallized alloys and in the alloys subjected to homogenizing heat treatment. Practical implications: The results of this research should allow obtaining homogenous microstructure in titanium alloys studied in this paper. Originality/value: The range of the temperature and strain rate for dynamic recrystallization restricting banding in the microstructure in the investigated alloys was determined. In the case of Ti-3Al-8V-6Cr-4Mo-4Zr alloy the range of the temperature and time of annealing leading to homogenization of the material was identified.
