{{0 {{}} Q: Dab tsi yog qhov tseem ceeb ntawm kev laus kev kho mob hauv aluminium alloys?
A: Kev laus kev kho yog ib qho kev kho cua sov tseem ceeb uas ua rau cov tshuaj kho cua sov thiab kev ua kom zoo nkauj thiab ua kom zoo nkauj Hom: Kev laus laus (hauv chav tsev kub, txhim kho lawv cov txheej txheem kub, txhim kho lawv cov txheej txheem thaum muaj kev cia siab thaum muaj kev tswj hwm kev ua haujlwm zoo rau engineering Kev Siv .
{{0 {{}} Q: aging aging kub cuam tshuam rau cov khoom ntawm txhuas alloys?
A: Kev laus kub profoundly cuam tshuam cov nag los nag thiab cov yam ntxwv kawg:
Qis dua kub (120-150 degree) tsim finer, ntau ntau cov precipitates, ua rau lub sijhawm siab dua ({1}} teev)
Kev Kub Ntxaij Nruab Nrab (150-175 degree) muaj kev sib npaug ntawm lub zog thiab lub sijhawm ua haujlwm ({1}} teev)
Ntau dua kub ({175-200 degree) ua rau coarser precipitates nrog kev txo me ntsis tab sis zoo dua qhov ruaj khov ({1}} teev)
Kev laus dhau kev laus dhau lub zog ncov zog Piv txwv, 6061 Txhuas siv 17 teev rau 8 teev mus txog 10 teev rau 10 teev rau 10 teev rau kev ua haujlwm zoo rau kev ua kom zoo dua.
{{0 {}} Q: Dab tsi yog qhov sib txawv tseem ceeb ntawm natural thiab cov txheej txheem kev laus?
A: Ntuj Laus (T4 Taus (T4 Taus Siab) thiab Txuj Ci (T6 TIV nyuaj) sib txawv hauv ntau qhov:
Lub Sij Hawm: Kev laus kev laus ntxiv rau ntau lub hlis ntawm chav sov, thaum muaj kev laus ua tiav hauv cov xuaj moos
Nag los: Ntuj Laus Cov Qauv GP Zones (cov pawg ntawm atoms), thaum cov laus dag tsim tawm cov theem ruaj khov zoo li θ 'lossis η'
Kev Txhim Kho Cov Khoom Siv: Kev laus laus feem ntau ua tiav 60-80% ntawm ntau tshaj plaws tau hardness, thaum lub sij hawm dag mus txog ncov lub zog
Ruaj khov: ib txwm laus alloys yuav txuas ntxiv hloov cov khoom maj mam, thaum muaj hnub nyoog rog tau ruaj khov
Cov Kev Siv: Kev laus laus yog siv thaum seem ruaj khov yog qhov tseem ceeb (e {{{{{{4}}}
{{04. Q: Kev ua kev laus ib txwm cuam tshuam rau corrosion tsis kam ntawm aluminium alloys?
A: Kev laus kev kho mob cuam tshuam rau kev coj tus cwj pwm ntawm corrosion:
Tsis muaj hnub nyoog (T4): Feem ntau zoo dua tsis kam rau intergranular corrosion tab sis qis zog
Peak-laus (T6)
Dhau-hnub nyoog (T7): Kev txi qee lub zog (10-15%) tab sis txhim kho kev ntxhov siab corrosion
Cov nyhuv nws txawv los ntawm Alloy Series:
2000 series (e {. g.}}}}}}}, 2024): T6 Temper yog nquag mus rau exfoliation corrosion; T7 Funper nyiam rau cov ntawv thov marine
6000 series (e {{{1} g .}}}}}}}}}}}, 6061): T6 muab qhov dav dav corrosion tsis kam
7000 series (e {{{{1} g}}}}}} 2}}, 7075): Xav kom tshwj xeeb (RRA) rau kev ua kom muaj zog-corrosion tshuav nyiaj li cas
{{0 {}} Q: Dab tsi yog qhov kawg nce hauv txhuas cov thev naus laus zis?
A: Tsis ntev los no kev txhim kho muaj xws li:
Rov ua dua tshiab thiab rov muaj hnub nyoog (RRA): ib kauj ruam peb-kauj ruam ntawm T6 nrog T7 Corrosion Kuj, tshwj xeeb rau 7000 series alloys
Tsis yog-yog-isothermal laus: Siv cov cua sov thiab cov nqi cua txias kom ua kom lub zog
Ultrasonic-pab kev laus: thov ultrasound thaum laus los ua kom nrawm diffusion thiab ua kom zoo nkauj
Tshuab Kawm Qauv Qauv: Kev kwv yees kev ua kom zoo rau kev ua kom zoo rau cov khoom lag luam alloy tshiab
Hauv-situ soj ntsuam: Siv hluav taws xob tiv taus lossis ntsuas ntsuas ultrasonic kom taug qab kev nce qib hauv lub sijhawm
Cov kev txhawb nqa no ua rau ntau yam kev tswj hwm tshaj ntawm kev txhim kho cov cuab yeej, pub rau cov ntawv thov customized hauv aerospace, thiab kev tsim kho kev lag luam, thiab kev tsim kho kev lag luam {}}
