Abstract NiTi alloys exhibit shape memory (SME), superelasticity (SE), and elastocaloric (eCE) effects, making them well for use as functional structural components. However, their poor machinability often limits them to simple geometries like plates, rods, and tubes. Unlike Ti6Al4V, Ni-based superalloy, and other load-bearing materials, SMAs require a balance of geometry, mechanical, and functional properties during fabrication. Laser Powder Bed Fusion (LPBF) 3D printing technology provides a solution for manufacturing shape memory alloys (SMAs) with intricate geometries. Despite extensive knowledge of process-structure-property relationships of LPBFed NiTi alloy, successful applications have yet to be widely reported. The challenge… More >
