Nitinol yog ib lub cim xeeb alloy. Shape memory alloy yog ib qho tshwj xeeb alloy uas tuaj yeem hloov kho nws tus kheej cov yas deformation rau nws cov duab qub ntawm qhov kub thiab txias, thiab muaj cov yas zoo.
Nws qhov kev nthuav dav yog siab dua 20%, qaug zog lub neej txog li 7 npaug ntawm 1 * 10, damping yam ntxwv yog 10 npaug siab dua li cov springs zoo tib yam, thiab nws cov corrosion kuj zoo dua li tam sim no kev kho mob stainless hlau, yog li nws muaj peev xwm ua tau raws li qhov xav tau ntawm ntau yam. engineering thiab kev siv kho mob, thiab nws yog ib yam khoom siv zoo heev.
Ntxiv nrog rau qhov tshwj xeeb zoo lub cim xeeb muaj nuj nqi, nco alloys kuj muaj cov yam ntxwv zoo xws li hnav tsis kam, corrosion kuj, siab damping thiab super elasticity.
(I) Theem Transformation thiab Properties ntawm Nickel-Titanium Alloys
Raws li lub npe qhia, Ni-Ti alloy yog binary alloy tsim los ntawm npib tsib xee thiab titanium, uas muaj ob lub qauv siv lead ua sib txawv, austenite thiab martensite, vim qhov kev hloov pauv ntawm qhov kub thiab txias thiab lub zog. Qhov kev txiav txim ntawm theem hloov ntawm Ni-Ti alloy thaum txias yog theem niam txiv (austenite theem) - R theem - martensite theem. R theem yog rhombic, austenite yog lub xeev thaum qhov kub thiab txias (ntau tshaj qhov qub: piv txwv li, qhov kub ntawm austenite pib), lossis de-loaded (sab nraud rog tshem tawm Deactivation), cubic, nyuaj. Cov duab yog ruaj khov dua. Lub sijhawm martensite yog qhov kub thiab txias (tsawg dua Mf: uas yog, qhov kub ntawm qhov kawg ntawm lub martensite) los yog kev thauj khoom (tsim los ntawm sab nraud quab yuam) thaum lub xeev, hexagonal, ductile, rov ua dua, tsis tshua muaj kev ruaj ntseg, ntau dua deformation.
