Effect of a constant laser energy density on the evolution of microstructure and mechanical properties of NiTi shape memory alloy fabricated by laser powder bed fusion

Control of microstructure and shape memory properties of a Fe-Mn-Si-based shape memory alloy during laser powder bed fusion

“…The pseudo-elastic and shape memory behavior has been defined by compression test of cylindrical samples (h/d = 1.5 [ 26 , 27 ]), as used for Ni-Ti-based [28][29][30] or Fe-Mn-Al-Ni-based [10] SMAs fabricated by LPBF. Cylindrical samples (5 mm diameter, 7.5 mm height, h/d = 1.5) were machined for compression tests from the fabricated blocks such that the LD of the samples corresponds to the BD.…”

A Review on Additive Manufacturing Methods for NiTi Shape Memory Alloy Production

“…This intricate process typically occurs within a preheated chamber under controlled temperature and atmosphere, often involving an inert gas depending on the specific material and processing parameters. Notably, variations in these parameters significantly influence the final product’s properties, encompassing its microstructure, mechanics, and even physicochemical characteristics [ 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ].…”

“…Each point represents the UTS value from various studies indicated by point shape. Black line shows linear fit, while shaded areas depict the corresponding 95% confidence intervals [ 20 , 35 , 41 , 54 , 55 , 57 , 60 , 114 ].…”
