Abstract
The vacuum brazing of hydrogenated TC4 titanium alloy containing different hydrogen content was carried out with Al brazing filler metal, and the interface structure and bonding strength of the joints were also investigated by means of SEM, XRD, EPMA and a testing machine. The experimental results showed that the interface structure consisted of two layers when the holding time was 45 min, and it only consisted of TiAl3 when the holding time was 90 min. The bonding strength gradually decreased with the increase of holding time, and the effects of hydrogen on bonding strength of the joints were obvious due to the higher bonding strength of the joints of hydrogenated TC4 alloy.
