Feem ntau suav nrog cov hlau nplaum sib nqus (saib cov ntaub ntawv sib nqus), cov hlau nplaum elastic, cov hlau nplaum nthuav dav, cov hlau nplaum thermal bimetals, cov hlau nplaum hluav taws xob, cov hlau nplaum hydrogen cia (saib cov ntaub ntawv cia hydrogen), cov hlau nplaum nco cov duab, cov hlau nplaum magnetostrictive (saib cov ntaub ntawv magnetostrictive), thiab lwm yam.
Ntxiv rau, qee cov alloys tshiab feem ntau suav nrog hauv pawg ntawm cov alloys precision hauv kev siv tswv yim, xws li damping thiab vibration reduction alloys, stealth alloys (saib cov ntaub ntawv stealth), magnetic recording alloys, superconducting alloys, microcrystalline amorphous alloys, thiab lwm yam.
Cov hlau nplaum raug muab faib ua xya pawg raws li lawv cov khoom sib txawv, uas yog: cov hlau nplaum mos, cov hlau nplaum ruaj khov uas tsis zoo, cov hlau nplaum elastic, cov hlau nplaum nthuav dav, cov hlau nplaum thermal bimetals, cov hlau nplaum tiv taus, thiab cov hlau nplaum thermoelectric ces kaum.
Feem ntau ntawm cov hlau sib xyaw ua ke yog ua los ntawm cov hlau ferrous, tsuas yog ob peb yam xwb yog ua los ntawm cov hlau uas tsis yog ferrous.
Cov hlau nplaum sib nqus suav nrog cov hlau nplaum mos mos thiab cov hlau nplaum sib nqus tawv (tseem hu ua cov hlau nplaum tas mus li). Cov thawj zaug muaj lub zog coercive qis (m), thaum qhov kawg muaj lub zog coercive loj (> 104A / m). Feem ntau siv yog cov hlau ntshiab hauv kev lag luam, hlau hluav taws xob, hlau-nickel alloy, hlau-aluminium alloy, alnico alloy, hlau cobalt tsis tshua muaj av, thiab lwm yam.
Thermal bimetal yog ib yam khoom sib xyaw ua ke uas muaj ob lossis ntau txheej ntawm cov hlau lossis cov hlau sib xyaw nrog cov coefficients nthuav dav sib txawv uas tau sib txuas ruaj khov rau ib leeg raws tag nrho qhov chaw sib cuag. Cov hlau sib xyaw ua ke siab siv ua txheej nquag, cov hlau sib xyaw ua ke qis siv ua txheej tsis siv neeg, thiab ib txheej nruab nrab tuaj yeem ntxiv rau hauv nruab nrab. Thaum qhov kub hloov pauv, cov hlau sib xyaw ua ke kub tuaj yeem khoov, thiab siv los tsim cov thermal relays, circuit breakers, cov khoom siv hauv tsev, thiab cov kua thiab roj tswj cov li qub rau kev lag luam tshuaj lom neeg thiab kev lag luam fais fab.
Cov khoom siv hluav taws xob suav nrog cov khoom siv tiv taus precision, cov khoom siv hluav taws xob electrothermal, cov ntaub ntawv thermocouple thiab cov ntaub ntawv tiv tauj hluav taws xob, thiab lwm yam, thiab siv dav hauv cov teb ntawm cov khoom siv hluav taws xob, cov twj paj nruag thiab cov ntsuas.
Cov hlau nplaum magnetostrictive yog ib chav kawm ntawm cov khoom siv hlau uas muaj cov teebmeem magnetostrictive. Feem ntau siv yog cov hlau nplaum thiab cov hlau nplaum nickel, uas yog siv los tsim cov ultrasonic thiab underwater acoustic transducers, oscillators, filters thiab sensors.
1. Thaum xaiv txoj kev siv tshuab ua kom cov hlau sib xyaw ua haujlwm tau zoo, feem ntau yuav tsum xav txog qhov zoo, tus nqi ntawm cov khoom siv hauv lub cub tawg, thiab lwm yam. Xws li xav tau kev tswj cov khoom xyaw kom raug, tshem cov pa roj carbon ntau dhau, txhim kho kev huv, thiab lwm yam. Nws yog ib txoj hauv kev zoo tshaj plaws los siv lub cub tawg hluav taws xob ntxiv rau kev ua kom huv sab nraum lub cub tawg. Raws li qhov yuav tsum tau ua kom zoo, lub cub tawg nqus tsev tseem yog ib txoj hauv kev zoo. Txawm li cas los xij, yuav tsum siv lub peev xwm loj dua li ntau tau.
2. Yuav tsum tau ua tib zoo saib xyuas cov txheej txheem nchuav kom tiv thaiv kev ua qias tuaj ntawm cov hlau molten thaum nchuav, thiab kev nchuav kab rov tav txuas ntxiv mus muaj qhov tseem ceeb tshwj xeeb rau cov hlau sib xyaw ua ke.
