Abstract:
      This paper addresses the issue of transient liquid phase diffusion bonding of pure titanium to 304 stainless steel using aluminum interlayer, at the temperature of 650 ℃ for 2 h under 2 MPa load in vacuum. Then the result was compared with the case of 550 ℃ and 600 ℃. The microstructures, chemical compositions and reaction products of the transition joints were revealed in SEM, EDS and XRD, respectively. The experimental results has shown that, the position of the transient liquid phase diffusion bonding interface is different from that of the conventional thermal diffusion, and aluminum play a mid sole element to prevent iron diffusion to titanium master alloys forming brittle intermetallic phase Fe-Ti. This paper introduces a new technique of Ti-Al-304 stainless steel composite plate diffusion bonding.
