Summary: This paper mainly studies the LPBF process optimization of Ni-Ti-Zr ternary alloy and reveals the evolution of microstructure, phase transformation behavior, and mechanical properties in LPBF-formed Ni-Ti-based shape memory alloy. The optimized process window range is determined to be 45-80 J/mm3 with the highest relative density of 98.89% under specific laser power, scanning speed, and preheat temperature. The addition of Zr significantly increases the phase transformation temperature and thermal hysteresis of Ni-Ti-Zr alloy, which broadens its application under high-temperature conditions and provides a theoretical reference for LPBF forming of high-performance nickel-titanium-based shape memory alloys.
