In this paper,it was addressed a hydrogen absorbing and desorbing thermodynamics in α+β type TC21 titanium alloy with high strength and toughness based on the
Solid-state diffusion bonding(DB)of TiAl alloy and Ti2AlNb alloy was carried out using pure Ti as an interlayer at 1000 ℃ under 20 MPa for 60-120 min.The effec
