Nitinol Sawb thiab Foil Description
Nitinol yog cov hlau alloy uas muaj cov khoom tshwj xeeb thiab siv tau, feem ntau yog tias nws tuaj yeem ua rau "nco" lossis hloov cov duab nyob ntawm qhov kub thiab txias. Lub npe sawv cev rau nws cov ntsiab lus thiab qhov chaw ntawm keeb kwm. Cov "Ni" thiab "Ti" yog cov cim atomic rau npib tsib xee thiab titanium thiab "NOL" sawv cev rau Naval Ordinance Laboratory qhov chaw uas nws tau pom nyob rau hauv 1959. Cov kws tshawb fawb tau sim tsim kom muaj cua sov thiab corrosive resistant alloy, thiab hauv cov txheej txheem ntawd. , tsim cov hlau ua los ntawm 55 feem pua nickel thiab 45 feem pua titanium.
Nitinol tau nyob ib puag ncig txij li thaum xyoo 1960s tab sis tsis tau ua lag luam mus txog nees nkaum xyoo tom qab, vim muaj kev tswj nruj uas xav tau hauv cov txheej txheem tsim khoom. Nws tau dhau los ua cov khoom tseem ceeb heev rau cov neeg tsim qauv ntawm cov neeg hlau thiab cov cuab yeej kho mob ntau xyoo dhau los. Nws cov superelastic (10X hloov tau raws li lwm yam hlau) thiab thermal zoo lub cim xeeb tsis zoo li lwm yam khoom siv rau engineering thiab kev tsim khoom.
Thaum nitinol sawb thiab ntawv ci nyob rau hauv lawv daim ntawv martensitic, lawv tau yooj yim deformed mus rau ib tug tshiab duab. Txawm li cas los xij, thaum lawv rhuab los ntawm kev hloov pauv kub, lawv rov qab mus rau austenite thiab rov zoo li qub nrog lub zog loj. Cov txheej txheem no hu ua kev nco.
Qhov kub ntawm lub alloy nco ntsoov nws cov ntawv kub siab thaum rhuab tuaj yeem hloov kho me ntsis ntawm cov alloy muaj pes tsawg leeg thiab los ntawm kev kho cua sov. Hauv cov nickel titanium alloys, nws tuaj yeem hloov pauv los ntawm saum toj no ntxiv rau 100 deg.C mus rau hauv qab -100 deg.C. Cov txheej txheem rov qab zoo li qub tshwm sim ntau dua li ob peb degrees thiab qhov pib lossis tiav ntawm kev hloov pauv tuaj yeem tswj tau nyob rau hauv ib qho degree lossis ob yog tias tsim nyog.
Nitinol sawb thiab ntawv ci kuj qhia tus cwj pwm superelastic yog tias deformed ntawm qhov kub thiab txias me ntsis saum lawv qhov kev hloov pauv kub. Cov nyhuv no yog tshwm sim los ntawm kev ntxhov siab vim tsim ntawm qee qhov martensite saum nws qhov kub thiab txias. Vim tias nws tau tsim los saum toj no nws qhov kub thiab txias, lub martensite reverts tam sim ntawd mus rau undeformed austenite sai li sai tau raws li qhov kev ntxhov siab raug tshem tawm. Cov txheej txheem no muab lub caij nplooj ntoo hlav, "rubberlike" elasticity hauv nitinol sawb thiab ntawv ci.
