(I) Canjin Lokaci da Kaddarorin Alloys na Nikel-Titanium
Kamar yadda sunan ke nunawa, Ni-Ti alloy wani allo ne na binaryar da ya ƙunshi nickel da titanium, waɗanda ke da nau'ikan tsarin sigar crystal daban-daban guda biyu, austenite da martensite, saboda canjin yanayin zafi da matsa lamba na inji. Tsarin canjin lokaci na Ni-Ti gami lokacin sanyaya shine lokacin iyaye (lokacin austenite) - lokaci R - lokaci martensite. Lokaci na R shine rhombic, austenite shine jihar lokacin da yawan zafin jiki ya fi girma (mafi girma fiye da ɗaya: watau, yawan zafin jiki wanda austenite ya fara), ko de-loaded (dakarun waje suna cire Deactivation), cubic, hard. Siffar ta fi kwanciyar hankali. Lokaci na martensite yana da ƙananan ƙananan zafin jiki (kasa da Mf: wato, zafin jiki na ƙarshen martensite) ko loading (wanda aka kunna ta dakarun waje) lokacin da jihar, hexagonal, ductile, mai maimaitawa, rashin kwanciyar hankali, mafi sauƙi ga nakasawa.
