Diffusion Bonding of Ti2AlNb-Based Alloy Using Spark Plasma Sintering Equipment
In the present paper, the effect of diffusion bonding (DB) and post-bond heat treatment on a microstructure and mechanical properties of a Ti2AlNb-based alloy VTI-4 was studied. DB was carried out using an SPS 10–3 selective plasma sintering system. The optimum mechanical properties of DB-joints (σu = 1240 MPa, σ0.2 = 1070 MPa, δ = 4.6%) were achieved after DB at temperatures of 940°C and 960°C, a holding time of 120 minutes, and a pressure of 15–25 MPa. The obtained mechanical properties were equal to that of the initial material (σu = 1230 MPa, σ0.2 = 1190 MPa and δ = 3.5%, 400 ± 10 HV0.2). After DB at 940–960°C, microhardness was 395 ± 30 HV0.2, which was higher than that after DB at 920°C (360 ± 25 HV0.2). DB provoked an increase in the volume fraction of the O-phase along the joint interface compared to the base material. Post-bond heat treatment resulted in an additional increase in the volume fraction of the O-phase that increased strength and hardness.
