Nov yog 5 cov lus nug thiab cov lus teb txog 2024 txhuas qhov kev pabcuam kub tshaj plaws, txhua tus teb hauv 5 kab lus:
Dab tsi yog qhov tseem ceeb tshaj plaws kub 2024 txhuas tuaj yeem tiv taus ua ntej kev puas tsuaj tas li?
2024 Aluminium pib ntsib kev ua kom muaj zog ploj ntawm 190 degree (374 degree f). Saum toj no 200 degree (392 degree f), nplej zom zaws ua rau muaj kev phom sij. Cov alloy poob 50% ntawm chav-kub lub zog ntawm 260 degree (500 degree f). Ua kom tiav Recrystallization tshwm sim thaum 415 degree (779 degree f). Cov kab mob no xav tias T3 \/ T4 Tawv Ntshav.
Yuav ua li cas 2024- t3 lub tshuab ua haujlwm degradade nrog kev kub ntxhov?
Tawm lub zog zuj zus los ntawm 345mpa ntawm 2 {{{{{}} degree rau 275mpa ntawm 120 degree. Ntawm 150 degree (302 degree f), qaug zog lub neej txo los ntawm 40% tiv thaiv chav kub. Elastic maculus txo qis linearly los ntawm 0.05gpa \/ degree saum 100 degree. Creep ua tus nqi tseem ceeb tshaj 120 Qib nyob rau hauv kev thauj khoom. Faa Item Mandates derating cov ntsiab lus rau cov dav hlau sib txawv saum 100 degree.
Vim li cas 2024 tsis haum rau JET JET lub cav cav txawm hais tias chav nyob zoo-kub?
Cov ntu ntawm ib txwm ua ib txwm muaj dua 200 degree thaum lub sijhawm ua haujlwm. Tooj liab-nplua nuj los nag nyob rau hauv 2024 coarsen sai sai saum 150 degree. Thermal Cycling ua rau microcack nucleation ntawm al2cu theem. Oxidation tus nqi nce 10 x dhau 175 degree hauv huab cua noo. Nickel-based alloys hloov nws nyob rau hauv cov kev kub-aav.
Qhov kev tiv thaiv kev tiv thaiv txuas ntxiv 2024 txoj kev siv tau kub?
Alodine 1200 Kev hloov pauv kev ntxiv ntxiv 20-30 degree thermal tsis. Tej hub thermal Teeb Meem Txheej Khaub Ncaws Yuav thawb txwv rau 300 degree luv luv. Anodizing txhim kho oxidation tsis kam txog 180 degree. Cladding nrog ntshiab txhuas pab nyob rau hauv cov xwm txheej cua sov sib txawv. Cov no ntxiv 15-25} lub txim tuag.
Yuav ua li cas 2024 tus stickal stability piv rau lwm tus aerospace aluminium alloys?
2219 khaws cov zog 50 Qib siab dua vim yog θ 'theem kev ruaj khov. 2618 Tsa cov khoom txog li 230 degree nrog FE \/ NI ntxiv. 7075 raug kev txom nyem dua lub zog poob saum toj no 120 degree los ntawm η theem kev sib cais. 6061 qhia tau zoo dua creep tsis kam tab sis qis heev lub zog. Kev xaiv cov khoom siv nyob ntawm qhov kub \/ kev ntxhov siab cov khoom siv.
