    • Abstract
  • Diffusion bonding test was performed on SP-700 titanium alloy hot rolled sheet, and the effects of diffusion bonding temperature (720, 750, 780, 810, 840 ℃) and time (5, 15, 30, 45 min) on the connection interface morphology and bonding strength were studied. The results show that with the increase of diffusion bonding temperature and time, the unbonded area of the alloy decreased until disappeared, and the interface bonding strength increased. The higher the temperature, the shorter the time interval required for fully integrating of the interface. When the bonding temperature was higher than 750 ℃ and time was 30 min, the interface was basically fully integrated. After diffusion bonding at 840 ℃ for 30 min, many equiaxed α phases existed on the bonding interface, and the interface bonding strength was the highest, reaching 400 MPa.
