Nitinol alyaj yo montre de byen ki gen rapò ak inik pwopriyete: efè memwa fòm (SME) ak superelasticity (SE; yo rele tou pseudoelasticity, PE). Fòm memwa se kapasite nan nitinol sibi deformation nan yon sèl tanperati, Lè sa a, refè orijinal li, fòm eneforme sou chofaj pi wo a "tanperati transfòmasyon" li yo. Superelasticity rive nan yon seri tanperati etwat jis anwo tanperati transfòmasyon li yo; nan ka sa a, pa gen okenn chofaj ki nesesè lakòz fòm nan ineforme yo refè, ak materyèl la montre elastisite menmen, kèk 10-30 fwa sa yo ki an metal òdinè.

Nitinol alloys exhibit two closely related and unique properties: shape memory effect (SME) and superelasticity (SE; also called pseudoelasticity, PE). Shape memory is the ability of nitinol to undergo deformation at one temperature, then recover its original, undeformed shape upon heating above its "transformation temperature". Superelasticity occurs at a narrow temperature range just above its transformation temperature; in this case, no heating is necessary to cause the undeformed shape to recover, and the material exhibits enormous elasticity, some 10-30 times that of ordinary metal.
