TA2/A3 has been investigated by means of OM. SEM, TEM, AES and XRD techniques. When the specimen is heat-treated at temperature under the β-Ti-α-Ti transformation. i.e., below 1173 K. only TiC forms along TA2 side of interface and hinders the interdiffuion of Fe and Tiatoins. thus Fe2Ti or FeTi is unable to occur. While it is treated up to the transformation temperature of β-Ti. e.g., over 1223 K, the parabolic growth of intermetallic compounds of Fe2Ti and FeTi with layer structure may form intergranularly and the formation of β-Ti or β-Ti + α-Ti structure at the Fe-enriched side of TA2 and of the martensitic transformation products at the Fe-depleted side were observed owing to diffusion of Fe. Furthermore, the growth of β-Ti transformation layer is revealed to follow the parabolic rule.
