Daim ntawv nco alloy yog lub martensitic theem hloov alloy nrog ib tug heev atomic kev npaj thiab ib tug ntim uas hloov mus rau tsawg dua 0.5%. Nws kuj yog qhov peb feem ntau hu ua nitinol zoo nco alloy. Qhov no alloy yuav deform nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam. Thaum lub zog sab nraud raug tshem tawm, nws tuaj yeem rov qab mus rau nws qhov qub. Qhov no qhia txog superelasticity ntawm nitinol zoo nco alloy. Thaum nyob rau hauv qee qhov kub thiab txias, nws tuaj yeem rov qab tau nws cov duab qub, uas qhia txog cov duab nco zoo ntawm nitinol zoo nco alloy.
Kev faib tawm ntawm cov duab nco alloys
1.) Ib-txoj kev nco nyhuv: Cov duab nco alloys deform ntawm qis kub thiab tuaj yeem kho lawv cov duab ua ntej deformation tom qab cua sov. Qhov zoo li lub cim xeeb tshwm sim uas tsuas muaj tshwm sim thaum lub sij hawm cua sov yog hu ua ib txoj kev nco nyhuv.
2.) Ob txoj kev nco txiaj ntsig: Nitinol alloy rov qab kho qhov kub-kub theem zoo thaum rhuab, thiab tuaj yeem kho qhov kub qis qis thaum txias, uas yog hu ua ob txoj kev nco.
3). nyhuv.
Kev faib tawm ntawm cov duab nco alloys
1.) Nitinol Hlau muaj lub cim xeeb zoo. Siv lub caij nplooj ntoos hlav ua los ntawm kev nco alloy ua piv txwv. Yog tias koj muab lub caij nplooj ntoos hlav zoo li no tso rau hauv dej kub, qhov ntev ntawm lub caij nplooj ntoos hlav yuav txuas ntxiv tam sim ntawd, thiab tom qab ntawd muab tso rau hauv dej txias, nws yuav tam sim ntawd rov qab mus rau qhov qub.
2.) Shape nco alloy muaj superelasticity, uas yog manifested nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam, nitinol puab nco alloy muaj ib tug ntau dua deformation rov qab muaj peev xwm dua li qub hlau, uas yog, lub loj strain generated thaum lub sij hawm loading txheej txheem yuav rov qab nrog unloading.
3).
4.) Nitinol nco hlau piv nrog cov ntaub ntawv magnetostrictive loj heev, tus nqi ntawm nitinol zoo nco alloy cov ntaub ntawv yog qis dua. Txij li cov ntaub ntawv loj loj magnetostrictive muaj ntau ntawm cov hlau kim (Tb), tus nqi ntawm cov khoom siv hlau nplaum nco tau yog kwv yees li ib feem kaum ntawm cov ntaub ntawv loj heev magnetostrictive.
5.) Nitinol Shape Memory alloys muaj ntau yam kev siv tseem ceeb. Sib nqus duab nco alloys, raws li cov ntaub ntawv ntse, yog cov khoom siv hauv paus rau yav tom ntej kev tiv thaiv hauv tebchaws thiab kev ua haujlwm siab. Nws cov yam ntxwv siab thiab cov lus teb siab yuav tsum tau siv rau hauv cov sensors, cov qauv ntse ntse, tsis siv neeg tswj, aircraft tis tswj systems thiab ultra-high-power ultrasonic transducer technology.
Hauv luv luv,puab nco alloymuaj ntau yam ntaub ntawv tshiab thiab cov teebmeem tshiab uas tsim nyog ntawm peb kev siv thiab kev tshawb fawb. Piv txwv li, muaj ib tug tshiab mechanism ntawm lub luag hauj lwm tseem ceeb ntawm magnetic teb nyob rau hauv lub martensitic theem transformation ntawm cov duab nco alloys. Nyob rau hauv txoj cai, lub magnetically induced duab nco nyhuv yog txawv kiag li los ntawm cov tam sim no nquag siv magnetostrictive nyhuv thiab los ntawm cov uas twb muaj lawm cov duab nco alloys thiab piezoelectric cov ntaub ntawv tswj los ntawm kub. Yog li ntawd, ntau yam ntaub ntawv tshiab thiab daim ntawv thov tshiab tuaj yeem tsim kho. Kev kho mob biocompatibility. Yog tias koj txaus siab rau nitinol nco alloy thiab xav paub ntau ntxiv txog nws, koj tuaj yeem tiv tauj amybai2010@zwmet.com txhua lub sijhawm. Raws li cov khoom siv ntse, sib nqus duab nco alloy yog cov khoom siv rau yav tom ntej kev tiv thaiv hauv tebchaws thiab kev ua haujlwm siab.
