| Abstract Scope |
Additive friction stir deposition (AFSD) is a novel friction stir-based additive manufacturing technique which utilizes contact friction to heat up the feedstock which is subsequently shear-deposited on the substrate. The tooling and process complexities to overcome for fabricating high strength alloys such as steels, nickel-based super alloys, and Ti alloys are indeed a challenge. Successful attempts have been made in the past to fabricate steels, Ti6Al4V, INCONEL 625, and complex concentrated alloys (CCAs). This work attempted to fabricate a laminated metal composite (LMC) using AFSD. SS316 and a CCA exhibiting transformation induced plasticity were utilized for fabrication. The mechanical property integration achieved in the LMC was analyzed from the perspective of strain partitioning between the individual alloys, and behavior of the interfaces. The detailed experiments, mechanical, and microstructural characterization performed in the study provides insights into fabrication of functionally graded materials and LMCs for property enhancement and integration using AFSD. |
