Toughness and Strength of Microstructurally Controlled Titanium Alloys.

Aza-Hibarigaoka, Tempaku-cho, Strength, toughness and microstructure relations in a:,cc + p and p titanium alloys are reviewed, auantitative fracture mechanisms of c(+p 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 I ) special heat treatments for producing desirable microstructures, 2) thermomechanical processing, 3) thermochemical processing incorporating cold work, and 4) deformation induced transformation.
