Abstract

Microlaminated TiB2-NiAl composite sheet consisting of alternating NiAl and TiB2-rich layers has been successfully fabricated. This fabrication method is composed of roll bonding for producing a multi-laminated Ni-(TiB2/Al) sheet from Ni sheets and TiB 2/Al composite sheets, and of subsequent annealing treatment for forming a NiAl intermetallic phase by reaction diffusion. Microlaminated TiB2-NiAl composite sheet obtained by this method exhibits strong {111}<μνω> texture. The formation mechanism of such texture by reaction diffusion has been discussed in view of texture inheritance. This method could utilize reaction diffusion to control texture component of materials, which is expected to provide an access to synthesize materials with texture for special requirement.
