Abstract Scope |
Friction-stir-based additive manufacturing (AM) technology has shown promising developments. Additive friction stir deposition (AFSD) is a solid-state AM process that uses frictional heating to plasticize workpiece material and deposit it in a layer-by-layer fashion to fabricate 3-dimensional structures. The AFSD process yields a fully dense wrought-like microstructure with minimal distortion and material wastage. AFSD state of the art has been well established for softer metallic materials like aluminum and magnesium. However, adaptation of AFSD for high-temperature materials is still challenging due to limited tool endurance and oxidation proneness. In this work, a feasibility study has been carried out to deposit a metastable β-Ti-5553 alloy using AFSD. Process-structure-property correlation has been established on the as-deposited alloy via detailed microstructural and mechanical property investigation. Further, mechanical property enhancement of the as-deposited alloy has been achieved by optimized post-process heat treatment. |
