Abstract

The growth of TiAl₃ is a critical stage during the fabrication of TiAl sheets employing Ti and Al sheets. In the present work, Al sheets were replaced by TiB₂/Al composites for (i) the production of TiB₂-TiAl composite sheets and (ii) a better deformation compatibility. The formation mechanism and growth kinetics of TiAl₃ layer in the multi-laminated Ti-(TiB₂/Al) composites were systematically investigated between 600°C and 650°C. The formation of TiAl₃ was a reaction-diffusion process accompanied by its order-disorder transition, its growth towards TiB₂/Al layers was found faster than that towards Ti layers. The introduction of TiB₂ particles had little influence on the growth of TiAl₃ layer which followed the parabolic growth law. The activation energy for growth of TiAl₃ layer was estimated to be 254.9kJmol^-1.
