is the high residual stress and rapid cooling rate. In comparison with fusion welding processes, diffusion bonding(DB) has the advantage that no melting of the base material occurs, which produces a drastic local change of the microstructure and related mechanical properties.

In particular, the bonding of advanced materials is not possible by classical welding methods because of unexpected phase propagation at the bond interface[2]. Hence, diffusion bonding......

point, coefficient of thermal conductivity, coefficient of linear expansion between the copper and steel[3]. At present, the high-quality welding joint was acquired often by adopting vacuum diffusion welding at home and abroad[4-11]. For the example, after the transient liquid phase(TLP) diffusion bonding of CuAlBe alloy to 1Cr18Ni9Ti using Cu30Mu alloy as interlayer, the strength of joint is up......
