FABRICATION OF (TiB₂+Fe)/Fe LAYERED MATERIALS BY SHS/QP PROCESS——ANALYSIS OF THE STRUCTURE AND PERFORMANCE

(TiB₂+Fe)/Fe layered materials were fabricated by SHS/QP process. SEM analysis showed TiB₂+Fe cermet layer in the layered material was fully dense. Interfacial bonding between TiB₂+Fe cermet and Fe substrate was analyzed by EPMA, which showed the interfacial bonding of two-layered product was obtained by the dissolution and the diffusion of TiB₂ in the Fe substrate and joining of Fe binder with Fe substrate. The fracture of joints took place in the TiB₂+Fe cermet layer rather than at the interface.
