✦ Synopsis

This article presents the results of investigations of microstructure and mechanical properties of two-phase ␣ + ␤ titanium alloys with different volume fraction of the ␤-phase. Microstructure of the specimens was examined using an optical microscope. Fracture surfaces were observed by SEM technique. The influence of the microstructure and phase composition on the mechanical properties of the alloys was studied. Static tensile tests, hardness tests and fatigue investigations were performed. It was noticed that the volume fraction and chemical composition of the ␤-phase has a significant effect on mechanical properties and cracking process during fatigue.
