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.

商业上的纯钛已扩散到各种碳含量的铁和钢；低碳钢，具有0.01％（ULC），具有0.19％C（S20C）的低碳钢和3.7K％C（FCD）的球形石墨壳。碳含量几乎不影响900 c低于900 c的关节的拉伸强度，并且随着粘结温度的升高而增加。然而，高于900 c的C，Ti-to-ulc接头的强度显示出恒定值，Ti-to-S20c接头的强度降低，而Ti-to-to-to-to-fcd的强度随着键合温度的升高而增加。沿键界面形成的层间仅由Ti-to-fcd关节中的抽动组成，Ti-to-to-to-ulc中的tife和tife_2。由于Ti和Fe在Ti-to-ulc中比Ti-to-to-to-fCD散布了，因此可以认为TIC层会干扰Ti和Fe的扩散，从而抑制抗乳房和TIFE_2的形成，从而降低了关节强度比TIC更加严重。 Ti-to-to S20C中的层中层由抽动和tife和tife_2组成。层中并存的碳化物和金属间化合物似乎比单独形成的碳化物降低了关节强度。
