A novel method to fabricate TiAl intermetallic alloy 3D parts using additive manufacturing

The present work explores the feasibility of fabricating porous 3D parts in TiAl intermetallic alloy directly from Ti-6Al-4V and Al powders. This approach uses a binder jetting additive manufacturing process followed by reactive sintering. The results demonstrate that the present approach is successful for realizing parts in TiAl intermetallic alloy.
