Abstract
A new theory for Ti alloy plastic deformation is proposed. Experiment results showed that a new kind of tri-modal miciostructure could be obtained using high temperature deformation strength - toughening. This microstructure strikingly raised low - cycle fatigue property, fatigue - creep interaction life, fracture toughness and service temperature of Ti alloy without reducing plasticity and thermal stability. The fundament of the new theory and strength - toughening mechanism bare also discussed. It was proved that high tem perature deformation strength - toughening was applicable not only in (α+β) alloy, but also in α, near α, and near β Ti alloy.
