AI Technical Summary
Existing technologies cannot simultaneously meet the integrated manufacturing requirements of complex titanium-steel heterogeneous components, such as formability, high interfacial bonding strength, absence of brittle phases, low residual stress, and high efficiency and low cost. In particular, there are difficulties in the preparation of complex internal cavities, variable cross sections, and gradient functional structures.
By employing a combined DED and SLM process, segmented temperature control and interface leveling, along with graded heat input regulation and optimized forming strategy, titanium-steel multi-metal integrated forming is achieved, suppressing brittle intermetallic compounds such as FeTi and improving the interfacial bonding strength and stability.
It achieves efficient and reliable forming of titanium-steel multi-material components, with excellent material interface properties, high interface bonding strength, reduced residual stress, and high yield. It is suitable for near-net-shape forming of complex structures, has strong adaptability, and is suitable for efficient mass production.
