Shenzhen University researchers reduced functional anisotropy in 4D-printed high-entropy shape memory alloys by integrating 1.0 wt.% TiN nanoparticles via LPBF. Grain size fell from 15.8 to 1.68 microns, cutting recovery strain anisotropy from 56.3% to just 3.4% after heat treatment. Yield strength reached 802.4 MPa, proving microstructural control can harmonize strength with predictable performance. This shift toward structural reliability is key for aerospace and robotics. 🚀 #4DPrinting #AM #Metals
