TiC-PHASE DIFFUSION LAYER FORMATION IN TITANIUM CLAD STEEL COMPOSITE HAVING AN INTERMEDIATE LAYER OFα-Fe
(Department of Materials Science and Engineering,Central South University of Technology, Changsha 410083)
Abstract: The TiC layer formed in the bond interface of the titanium clad steel composite having an intermediate layer of α-Fe at 1023K for different times was examined metallographically and analyzed using an electron microprobe technique.The mechanism of TiC phase diffusion layer formation was discussed by Fick’s law assuming that stationary diffusion of carbon was established in titanium/α-Fe/steel diffusion couples.
Key words: TiC-phase carbon activity stationary diffusion
