Strength, toughness and microstructure relations in α,α + βand β titanium alloys are reviewed. Quantitative fracture mechanisms of α + β titanium alloys are described from the view point of strain-controlled ductile fracture models based on fracture mechanics. Various strengthening and toughening processes of titanium alloys are described in relation to 1) special heat treatments for producing desirable microstructures, 2) thermomechanical processing, 3) thermochemical processing incorporating cold work, and 4) deformation induced transformation.
