Research was conducted during this effort to define the relationship(s) between mechanical properties and crystallographic texture development in three commonly used alpha + gamma Ti alloy compositions. Texture development was monitored during the conversion of production ingot stock to one quarter inch thick rolled plate as a function of thermomechanical processing. The three alloy compositions were 6Al-4V Ti ELIGrade, 6Al-4V Ti Standard Grade, and 6Al-2Sn-4Zr-6Mo Ti. Sufficient quantities of one specific textural type, basal transverse, were produced for all three compositions to permit extensive mechanical and fracture property testing at room and elevated temperature as a function of product orientation. Material properties evaluated were elastic modulus, monotonic stress--strain behavior, cyclic stress--strain behavior, notched and unnotched fatigue, and fracture toughness (Resistance Curves).
