Cov ntaub ntawv txhuas yog cov khoom siv tau ntau yam thiab siv dav hauv kev tsim cov khoom forged. Cov yam ntxwv tshwj xeeb ntawm txhuas ua rau nws zoo tagnrho rau ntau yam kev siv, los ntawm cov khoom siv hauv tsheb mus rau cov khoom siv dav hlau.
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm kev siv cov txhuas profile los tsim cov khoom forged yog nws qhov sib dua. Aluminium yog sib dua li hlau, ua rau nws yog qhov kev xaiv zoo rau cov ntawv thov uas qhov hnyav yog qhov tseem ceeb. Qhov no ua rau nws tsim nyog siv rau hauv kev lag luam aerospace, qhov twg qhov hnyav txuag tau tuaj yeem ua rau txuag roj ntau thiab ua haujlwm tau zoo dua.
Ntxiv rau qhov tsis hnyav, cov profiles txhuas muaj lub zog zoo heev thiab ruaj khov. Thaum forged kom raug, txhuas tuaj yeem ua rau muaj zog tab sis resilient khoom uas tuaj yeem tiv taus qhov nyuaj ntawm kev siv hnyav. Qhov no ua rau nws yog cov khoom siv zoo tagnrho rau ntau yam kev siv, los ntawm cov khoom siv qauv mus rau cov khoom ua tau zoo.
Lwm qhov zoo ntawm kev siv cov txhuas profile los tsim cov khoom forged yog nws txoj kev tiv thaiv corrosion. Aluminium ntuj tsim ib txheej oxide tiv thaiv thaum raug cua, pab tiv thaiv xeb thiab corrosion. Qhov no ua rau nws yog qhov kev xaiv zoo heev rau kev siv sab nraum zoov lossis qhov chaw uas muaj av noo siab.
Tsis tas li ntawd xwb, cov txhuas profiles yog cov ductile heev thiab tuaj yeem yooj yim forged rau hauv cov duab thiab cov qauv tsim nyuaj. Qhov no ua rau nws yog cov khoom siv zoo tagnrho rau kev tsim cov khoom tshwj xeeb thiab cov khoom tshwj xeeb uas yuav nyuaj lossis tsis yooj yim sua los tsim siv lwm cov ntaub ntawv.
Hauv kev xaus lus, cov ntaub ntawv txhuas yog cov khoom siv ntau yam uas zoo rau kev tsim cov khoom forged. Nws qhov hnyav sib dua, lub zog, kev ruaj khov, kev tiv thaiv corrosion thiab ductility ua rau nws zoo tagnrho rau ntau yam kev siv. Txawm hais tias siv rau hauv kev lag luam aerospace, kev lag luam tsheb lossis cov khoom tshwj xeeb, cov ntaub ntawv txhuas muab kev sib xyaw ua ke zoo meej ntawm cov khoom, ua rau lawv yog thawj qhov kev xaiv rau kev forging cov khoom zoo.
