In the paper results of the investigation on the effect of microstructure on room temperature tensile properties and fracture toughness of two-phase alpha+beta titanium alloy Ti-6Al-2Mo-2Cr have been presented. Microstructure has been varied by changes in the cooling rate from the solution treatment temperature and ageing time and temperature. Mechanical properties examined show strong dependence on the heat treatment conditions, especially aging conditions. It has been attributed mainly to amount and morphology of alpha phase obtained after heat treatment. The higher volume fraction of lamellar alpha phase, and the coarser the lamellar alpha structure, the higher the fracture toughness.
