“…Relevant researches on the selective laser melting (SLM) fabricated NiTi alloy are mainly concentrated on the processing optimization with both pre-alloying powder [6][7][8][9][10][11][12][13][14][15][16][17][18] and mixed pure powders [19] as starting powder materials, the measurement of martensitic transformation temperatures [6][7][8][9][10][11][12][13][14][15][16][17][18], the detection of the stress or strain-induced martensitic transformation from different thermomechanical conditions [10,12,15,[16][17][18], the effect of post-heat treatment [10,12], evaluation of other functional properties such as the damping properties [6] and the fatigue behavior [13,14]. Based on these numerous investigations, it is worth noting that it exists large discrepancies in results, especially in terms of the final mechanical properties and shape memory effects.…”

“…As the origin of functional properties of NiTi alloy, the MT indeed plays a crucial role in the final processing and optimization. That is why the MT temperatures [6][7][8][9][10][11][12][13][14][15][16][17][18] and the critical stress inducing the martensitic transformation [10,12,15,[16][17][18] are widely investigated by most of…”

“…Such efforts have led many to question the use of materials designed for traditional wrought processes in AM and research has evolved to study the effects of AM processing on more unusual materials such as intermetallics. Specific work in intermetallics has been focused on materials such as titanium aluminides for high temperature strength, oxidation resistance, and creep resistance in the aerospace industry [1][2][3][4], or nickel titanium intermetallics for shape memory, damping, and biocompatibility for implants in the medical industry [5][6][7][8][9]. Only a few publications have investigated the potential for the selective laser melting (SLM) of magnetic intermetallics [10][11][12][13].…”

“…The slight decrease in free vibration frequency when the SMA temperature changed from T ( T 1 to T % T 1 is possibly an effect of the R-phase, a trigonal lattice with a martensitic nature that can be attributed to composition inhomogeneity. 25,26 At temperatures greater than 45 C, the oscillation frequency increased to 41.1 Hz. The damping ratio values were estimated (by the logarithmic decrement method) as 0.0072 and 0.0043 for the low-and hightemperature cases, respectively.…”
