Kev txhais thiab lub ntsiab cai
Permany alloy cov hlau nplaum xa mus rau sib nqus alloys uas tuaj yeem khaws lub siab rov qab tom qab tau muab hlau nplaum thiab sab nraud sib nqus. Lawv cov hlauetism keeb kwm los ntawm cov qauv ua haujlwm tshwj xeeb thiab cov kev npaj ntawm lub sijhawm sib nqus hauv cov alloy. Ntawm lub microscopic, cov atomic sib nqus lub hli nyob rau hauv Alloy Daim Ntawv Sib Nqus Thawj. Thaum tsis muaj ntawm qhov sib nqus sab nraud sib nqus, cov lus qhia ntawm cov sib nqus ntawm cov hlau nplaum yog faib cov khoom sib nqus tau, thiab cov vector suav ntawm lub sijhawm sib nqus tag nrho yog ze rau xoom. Tom qab cov teb sab nraud sib xyaw ua ke, cov sib nqus hlau yuav rov qab ua raws cov kev sib nqus ntawm cov sib nqus sab nraud, yog li nthuav tawm macroscopic Magnetism.
Lub ntsiab
Tsis tshua muaj lub ntiaj teb tsis muaj peev xwm sib nqus alloys: xws li neodymium hlau boron (SMCO), tab sis nws cov tshuaj lom neeg thiab cov tshuaj ruaj khov yog cov tsis zoo. SMCO, ntawm qhov tod tes, muaj siab tiv taus qhov kub thiab txias, oxidation thiab corrosion. Alnico ruaj khov sib nqus allots: lawv muaj cov khoom sib nqus siab thiab muaj peev xwm ua kom muaj zog sib nqus hauv qhov chaw siab sib nqus, tab sis kev quab yuam kom tsawg. Ceeb toom cov khoom sib nqus tas li Alloys xws li 2j21 thiab 2j23 muaj zoo hysteresis yam ntxwv hauv nruab nrab thiab siab ua haujlwm ua haujlwm sib xyaw. Manganese-aluminium-cov pa roj sib nqus Sib khi lus tsis tshua muaj zog av lub ntiaj teb cov khoom sib nqus: lawv tau ua los ntawm cov duab sib nqus nrog cov nyom, tab sis lawv cov khoom siv tsis tshua muaj zog, tab sis lawv cov khoom sib nqus tsis tshua muaj zog, tab sis lawv cov khoom sib nqus tsis tshua muaj zog, tab sis lawv cov khoom sib nqus tsis tshua muaj zog, tab sis lawv cov khoom sib nqus tsis tshua muaj zog thiab muaj peev xwm qis dua cov ntawm cov hlau nplaum sib tw.
Cov yam ntxwv ua tau zoo
High Motannetism: lawv muaj kev sib zog siab, siab ua kom muaj zog thiab muaj peev xwm tsim cov khoom sib nqus muaj zog, thiab tuaj yeem tsim cov khoom sib nqus muaj zog hauv ib qho hluav taws xob me me thiab nrog lub teeb hnyav. Cov khoom ruaj khov zoo: nyob rau hauv qee qhov kev mob ib puag ncig xws li cua sov thiab av noo, lawv tuaj yeem tswj cov khoom sib nqus ruaj khov thiab tsis yooj yim rau demagnetize. Qee qhov kev sib nqus sib nqus tas li xws li SMCO thiab Alnico muaj qhov siab zoo-kub tsis kam thiab tuaj yeem ua haujlwm ib txwm nyob hauv ib puag ncig kub-kub. Muaj zog corrosion: qee qhov kev kho mob sib nqus tas mus li, muaj kev ua kom zoo rau cov neeg muaj kuab, acid thiab alkali. Cov cuab yeej ua kom zoo: lawv muaj qee qhov kev nyuaj siab thiab muaj zog, tuaj yeem tiv thaiv ib qho kev quab yuam sab nraud, thiab tuaj yeem ua kom tau raws li cov kev xav tau ntawm cov neeg kho tshuab sib txawv.
