Khoom Taw qhia

Lub peculiar nta ntawm nitinol tshwm sim los ntawm ib tug reversible solid-state theem hloov hu ua ib tug martensitic transformation, uas xav tau ntawm 10, 000 thiab 20, 000 psi (69 thiab 138 MPa) ntawm txhua yam kev nyuaj siab tshwm sim ntawm ob qhov sib txawv martensite crystal theem.

Austenite, tseem hu ua niam txiv theem, yog qhov cuam tshuam yooj yim cubic qauv uas nitinol tau txais ntawm qhov kub thiab txias. Nitinol spontaneously hloov mus rau hauv lub martensite (tus ntxhais theem), ib tug complex monoclinic siv lead ua qauv, nyob rau hauv uas tsis muaj kub.The austenite-to-martensite thiab martensite-rau-austenite transformations muaj plaub yam kev hloov pauv kub. Raws li cov hlau txias txias rau qhov hu ua martensite pib kub, lossis Ms, martensite pib tsim los ntawm tag nrho austenite, thiab qhov kub ntawm qhov kev hloov pauv tiav yog hu ua martensite tiav kub, lossis Mf. Austenite pib tsim ntawm austenite pib kub, Raws li, thiab xaus ntawm austenite tiav kub, Af, thaum lub alloy yog rhuab thaum nws yog tag nrho martensite.Cov kab lus no yog hais txog Nitinol Sheet.

Keeb kwm

Lub npe "Nitinol" yog muab los ntawm cov hlau cov tshuaj pleev ib ce thiab Naval Ordnance Laboratory, qhov twg nws tau xub pom. Nws cov txiaj ntsig tau pom nyob rau xyoo 1959 thaum William J. Buehler thiab Frederick Wang tab tom ua kev tshawb fawb ntawm Naval Ordnance Laboratory.Buehler tau ua haujlwm los tsim kom muaj lub ntsej muag lub ntsej muag zoo dua uas tuaj yeem tiv taus hnav thiab tsim kua muag, cua sov, thiab cuam tshuam lub zog. Nws tau nthuav tawm ib qho piv txwv ntawm lub rooj sib tham hauv chav kuaj hauv xyoo 1961 tom qab pom tias 1: 1 alloy ntawm nickel thiab titanium tuaj yeem ua tiav txoj haujlwm. Cov qauv raug xa mus rau ib puag ncig thiab flexed los ntawm cov neeg koom tom qab tau muab tais zoo li accordion. Rau txhua tus neeg xav tsis thoob, lub accordion-shaped strip shrink thiab rov qab mus rau nws cov duab qub tom qab ib tus ntawm lawv tau sov cov qauv nrog nws cov yeeb nkab sib zog.

Nitinol cov ntawv thov muaj peev xwm nkag siab tau yooj yim, tab sis kev siv dag zog ua lag luam tsis tau pib txog kaum xyoo tom qab. Qhov tshwj xeeb teeb meem ntawm melting, refining, thiab machining lub alloy yog ib qho tseem ceeb contributor rau no ncua. Txawm tias cov kev pib no tau khiav mus rau qhov teeb meem nyiaj txiag uas tsis yooj yim kov yeej kom txog rau thaum xyoo 1980s, thaum cov teeb meem tiag tiag hauv ntiaj teb pib pib kho.
