Shape memory effect of nitinol
Webb15 juli 2024 · Nitinol (nickel–titanium) shape memory alloy (SMA) is of great interest as a biomedical implant or medical device material, due to its distinctive superelastic behaviour and shape memory effect, over and above its good biomechanical biocompatibility due to its low modulus, excellent wear resistance, higher ductility, and higher strength [16], [29]. WebbNitinol has two characteristics: shape memory effect (SME) and superelasticity (SE). Shape memory happens when mother phase of a certain shape is cooled from above the …
