Nyob rau hauv cov nqe lus ntawm lub zog, tooj liab xaim qhia lub zog tensile nruab nrab, uas yog qhov siab tshaj plaws ntawm tensile kev nyuaj siab nws tuaj yeem tiv taus ua ntej tawg. Lub zog tiag tiag ntawm tooj liab hlau tuaj yeem sib txawv nyob ntawm nws qhov tshwj xeeb alloy thiab txheej txheem tempering. Copper alloys nrog qib siab ntawm alloying ntsiab, xws li tooj liab lossis tooj dag, tuaj yeem txhim kho lub zog piv rau cov tooj liab ntshiab.
Txawm hais tias tooj liab hlau yuav tsis phim lub zog ntawm lwm yam ntaub ntawv, nws compensates nrog nws zoo heev yooj thiab ductility. Copper yog cov hlau uas tuaj yeem ua tau yooj yim, ua rau nws yooj yim tsim rau hauv cov xov hlau sib txawv thiab cov duab. Qhov kev hloov pauv no yog qhov zoo rau cov ntawv thov uas xav kom cov hlau yuav tsum tau khoov, twisted, los yog zoo li tus kom haum rau cov kev xav tau tshwj xeeb.
Ntxiv mus, tooj liab hlau qhia tau zoo kawg nkaus toughness, uas yog hais txog nws lub peev xwm nqus tau lub zog thiab tiv thaiv tawg nyob rau hauv kev cuam tshuam los yog tam sim ntawd loads. Toughness yog cuam tshuam los ntawm ob qho tib si lub zog thiab ductility, thiab tooj liab lub hauv paus ductility pab txhawb rau nws toughness. Copper hlau tuaj yeem tiv taus kev khoov thiab deformation yam tsis muaj kev tawg yooj yim, ua rau nws tsim nyog rau cov ntawv thov uas nws raug rau cov neeg kho tshuab kev ntxhov siab lossis kev vibrations.
Lub siab toughness ntawm tooj liab hlau kuj ua rau nws tiv taus thermal expansion thiab contraction yam tsis muaj kev puas tsuaj loj. Copper lub peev xwm los ua kom haum rau cov kev ntxhov siab thermal ua rau nws tsim nyog rau cov ntawv thov hauv cov tshuab hluav taws xob, qhov twg qhov kub thiab txias sib txawv.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias qhov tshwj xeeb lub zog thiab lub zog toughness ntawm tooj liab hlau tuaj yeem txhim kho ntxiv los ntawm ntau txoj hauv kev. Piv txwv li, tooj liab hlau tuaj yeem ua alloyed nrog lwm cov hlau los txhim kho nws lub zog thaum tswj cov hluav taws xob zoo. Tsis tas li ntawd, cov txheej txheem kho cua sov, xws li annealing lossis txias ua haujlwm, tuaj yeem ua haujlwm los hloov kho cov khoom siv hluav taws xob raws li qhov xav tau.
Hauv cov ntsiab lus, thaum tooj liab hlau yuav tsis muaj lub zog tshwj xeeb piv rau lwm cov ntaub ntawv, nws yooj yim, ductility, thiab toughness ua rau nws muaj ntau yam kev xaiv rau ntau daim ntawv thov. Copper hlau muaj peev xwm ua tau yooj yim zoo li tus thiab tiv taus deformation yam tsis muaj kev puas tsuaj ua rau nws siv tau hauv cov tshuab hluav taws xob, xov hlau, thiab lwm yam kev siv tshuab. Nws ua ke ntawm hluav taws xob conductivity thiab cov khoom siv kho tshuab txuas ntxiv ua rau nws muaj txiaj ntsig zoo hauv ntau yam lag luam.
