Implication

Experimental study demonstrates energy density controls superelasticity in additive Ni51.3Ti48.7 shape memory alloy, highlighting optimal parameters for enhanced functional recovery.

Key Points

Laser powder bed fusion energy density regulates phase transformation and superelasticity in nickel-rich Ni51.3Ti48.7 alloys by limiting nickel evaporation during fabrication.
Lower energy density yields superior superelasticity, achieving maximum recovery rates of 5.7% during initial loading and 5.3% after repeated cycling.
Microstructural analysis shows reduced heat input preserves the austenite phase at room temperature, suggesting tailored processing can optimize functional shape memory alloy components.
