Aluminium barsnyob rau hauv txawv teb thiab txawv teb ntawm txhuas bar kev ua tau zoo cov kev cai tsis zoo ib yam, nyob rau hauv mechanical processing thiab lwm yam kev lag luam, lub compressive zog ntawm txhuas tuav yog tshwj xeeb tshaj yog nruj, uas stipulates tias nyob rau hauv cov txheej txheem ntawm txhuas tuav los ua hardening kev kho mob, thiaj li yuav txhim kho lub compressive zog ntawm txhuas tuav, thiaj li ua tau raws li qhov yuav tsum tau ua. Nyob rau theem no, muaj ob txoj hauv kev tsim khoom thiab kev ua tiav, uas yog, kev tsim khoom thiab kev ua kom muaj zog thiab kev daws teeb meem. Ob txoj hauv qab no yog luv luv thiab nthuav dav: ntau lawm thiab ua kom muaj zog aluminium bar.
Kev tsim khoom thiab kev ua kom muaj zog, tseem hu ua txias ua hauj lwm hardening, yog qhov txias deformation ntawm txhuas tuav ntawm cov nram qab no recrystallization kub, xws li forging, calendering, kos duab, ncab, thiab lwm yam., thaum txias deformation, lub sab hauv dislocation ceev ntawm txhuas tuav, thiab lawv intertwine nrog ib leeg thiab tsim cellular qauv, uas cuam tshuam dislocation. Qhov loj dua tus nqi deformation, qhov loj dua qhov dislocation entanglement, ntau dua qhov deformation kuj thiab siab dua lub zog compressive. Cov degree ntawm hardening tom qab txias deformation txawv nrog deformation degree, deformation kub thiab cov khoom ntawm raw cov ntaub ntawv. Thaum tib yam raw khoom yog txias deformed ntawm tib qhov kub, qhov siab dua tus nqi deformation yog, qhov siab dua lub zog compressive yog, thiab qis dua cov yas yog.
Los ntawm kev ntxiv qee cov ntsiab lus alloying rau cov ntshiab txhuas los tsim cov tshuaj tsis kawg los yog cov khoom siv finite, tsis tsuas yog siab compressive zog, tab sis kuj zoo heev plasticity thiab kev ua tau zoo ntawm siab ntau lawm thiab ua tau. Tooj, magnesium, manganese, zinc, silicon, npib tsib xee thiab lwm yam khoom siv feem ntau siv hauv cov khoom siv ntxiv dag zog ntawm Shenyang txhuas tuav. Feem ntau, txhuas pas nrig alloying tsim cov kev daws teeb meem zoo, xws li Al-Cu, Al-Mg, Al-Zn, Al-Si, Al-Mn thiab lwm yam binary alloys, uas txhua tus muaj cov kev txwv loj heev thiab tuaj yeem muaj cov tshuaj loj heev ntxiv zog.
Los ntawm kev ntxiv dag zog rau aluminium bar, nws lub zog compressive yuav zoo dua, tab sis nws lub zog compressive tsis tuaj yeem txhim kho tas li; Thaum lub siab tshaj plaws compressive zog mus txog, txawm tias siv txoj kev twg, lub zog compressive ntawm aluminium bar tsis tuaj yeem txhim kho ntxiv. Qhov kev xaiv nkaus xwb yog xaiv lub hom nrog lub zog compressive ntau dua.
