Abstract
The microstructure together with the formation and growth of reaction phases in the interfacial diffusion zone of the explosive cladding TA2/A3 has been investigated by means of OM, SEM, AES and XRD techniques. When the specimen annealed at temperature under theβ-Ti→α-Ti transformation, i. e. below 1 173 K, only TiC forms along TA2 side of interface and hinders the interdiffusion of Fe and Ti atoms, thus Fe2Ti or FeTi is unable to occur. While heated up to the transformation temperature ofβ-Ti, e. g, over 1 223 K, the parabolic growth of intermetallic compounds of Fe2Ti and FeTi with layer structure may form intergranularly and the formation ofβ-Ti orβ-Ti+α-Ti structure at the Fe enriched side of TA2 and the martensitic transformation products at the Fe-depleted side are observed owing to the diffusion of Fe. Furthermore, the growth ofβ-Ti transformation layer is revealed to follow the parabolic rule.
