Abstract

The bonding of Ti-6Al-4V to low alloy steel (AISI4330) using SPS technique in the 850-950°C temperature range was examined. The formation of a thin (∼1 μm) titanium carbide interfacial layer was observed with a thickness only slightly dependent on the joining temperature. This layer separates the joined metals and prevents the formation of Fe-Ti intermetallics in the bonding zone. The maximal tensile strength of the joints (of about 250 MPa) was achieved for bonding at 950°C for 3.6 ks. The formation of the titanium carbide layer and its evolution are discussed based on the isothermal section of the ternary Fe-Ti-C phase diagram.
