A commercially pure titanium has been diffusionbonded to iron and steels of various carbon contents;low carbon steel with 0.01%(ULC), mild steel with 0.19%c(S20C) and spheroidal graphite case iron with 3.7k%c(FCD). The tensile strength of joints bonded below 900゜C was hardly influenced by the carbon content, and increased with the rise in bonding temperature. above 900゜C, however, the strength of the Ti-to-ULC joint showed a constant value, that of the Ti-to-S20C joint decreased, and that of the Ti-to-FCD increased with the rise in bonding temperature. The interlayer forming along the bond interface consisted only of TiC in the Ti-to-FCD joint and of TiFe and TiFe_2 in the Ti-to-ULC. Since Ti and Fe diffused over much longer distances in the Ti-to-ULC than in the Ti-to-FCD, the TiC layer may be considered to interfere with the diffusion of Ti and Fe, and consequently to suppress the formation of TiFe and TiFe_2 which decrease the joint strenght more seriously than TiC. The interlayer in the Ti-to S20C consisted of TiC as well as TiFe and tife_2. The coexisting carbide and intermetallic compounds in the interlayer, seems to reduce the joint strength to a more extent than those formed individually.

工业纯钛已扩散结合到各种碳含量的钢铁上：0.01%c 的低碳钢（ULC）、0.19%c（S20C）的低碳钢和 3.7k%c（FCD）的球墨铸铁。 900℃以下的接头强度几乎不受碳含量的影响，并且随着接头温度的升高而增加。然而，在900゜C时，Ti-to-ULC接头的强度呈现恒定值，Ti-to-S20C接头的强度随着粘合层间温度的升高而下降，而Ti-to-FCD的强度则增加。由于 Ti 和 Fe 在 Ti-to-FCD 接头中形成的粘结界面仅由 TiC 组成，而在 Ti-to-ULC 接头中则由 TiFe 和 TiFe_2 组成。 Ti-to-ULC与Ti-to-FCD相比，TiC层可能会干扰Ti和Fe的扩散，从而抑制TiFe和TiFe_2的形成，TiFe和TiFe_2比TiC更严重地降低了接头强度。 Ti-to S20C 中的中间层由 TiC 以及 TiFe 和 tif_2 组成。中间层中共存的碳化物和金属间化合物似乎比形成的接头强度更大程度地降低了接头强度。单独。
