6061 T6 txhuas, muab los ntawmGNEE, yog cov khoom siv dav siv uas xa cov kev ua tau zoo dua piv nrog ntau lwm qib. Nws lub zog siab, kev tiv thaiv corrosion, thiab muaj peev xwm ua tau raws li kev kho cua sov- xws li temper conditioning - ua rau nws muaj kev cia siab rau cov khoom xws li tsheb kauj vab thav duab mus rau cov khoom lag luam.
Kab lus no piav qhia txog qhov zoo ntawm 6061 T6 tshaj lwm cov alloys, nws cov nqi -cov txiaj ntsig zoo, thiab vim li cas nws thiaj siv thoob plaws kev lag luam sib txawv. Nws tseem hais txog cov kev txhawj xeeb thiab cov lus nug uas cuam tshuam txog nws txoj kev ntseeg siab hauv cov ntawv thov tseem ceeb.
6061 T6 Ua li cas?
Kev tsim khoom ntawm 6061 T6 txhuas yog cov txheej txheem ua tib zoo tswj tau tsim kom ua tiav cov khoom siv kho tshuab thiab lub cev zoo uas txhais cov hlau.
Cov ntsiab lus alloying tseem ceeb suav nrog silicon thiab magnesium, nrog rau me me ntxiv ntawm tooj liab thiab chromium los txhim kho corrosion kuj thiab kav ntev. Cov ntsiab lus no pab txhawb rau nws lub zog siab thiab kev ua haujlwm qaug zog, ua rau cov hlau tsim nyog rau kev thov kev thov.
Cov txheej txheem pib los ntawm melting raw aluminium thiab blending nws nrog alloying ntsiab los tsim ib tug sib tov sib xyaw uas tshem tawm cov kev ntxhov siab sab hauv.
Qhov sib tov no ces muab pov rau hauv billets, uas tom qab ua tiav rau hauv nplooj ntawv, phaj, raj, thiab tuav ua raws li Aluminium Association cov qauv.
T6 temper yog ua tiav los ntawm ib tug tshwj xeeb cua sov- kho ib ntus - kev kho cua sov kev kho mob raws li cov khoom siv dag zog aging- uas ua rau kom hardness thiab yield zog nyob rau hauv 6061 T6 khoom.
Lub Temper System
| Kub | Lub ntsiab lus |
|---|---|
| T | Thaum tshav kub kub kho - tshuaj kho thiab hnub nyoog (T6=tshuaj + kev laus laus) |
| O | Annealed - siab mos, siab tshaj plaws ductility, rau kev sib sau |
| H | Strin hardened (txias ua hauj lwm)-lub zog nruab nrab, txo ductility |
| F | Raws li fabricated - tsis txhob txhob txwm kub siab kho mob |
Cov txheej txheem kev kho cua sov kom ntxaws ntawm 6061 T6
Txhawm rau ua kom tau raws li cov kev xav tau ntawm daim ntawv thov-tshwj xeeb tshaj yog nyob rau hauv aerospace thiab marine sectors-kev kho cua sov ntawm 6061 T6 txhuas yog qhov tseem ceeb. Cov txheej txheem suav nrog:
Kauj Ruam 1 - Kev kho cua sov
Kub mus txog515-530 degree(ze tab sis qis dua qhov kub ntawm eutectic melting).
Magnesium thiab silicon yaj rau hauv cov txhuas matrix, tsim cov khoom sib xws.
Lub sij hawm ntawm qhov kub thiab txias nyob ntawm seem thickness; tsis txhob overheating, uas ua rau eutectic melting thiab weakens lub alloy.
Kauj ruam 2-Quenching
Kev txias nrawm (feem ntau yog dej quenching) xauv cov ntsiab lus alloying hauv cov kua dej supersaturated;
Tiv thaiv kom tsis txhob muaj qhov loj, tsis yog - ntxiv dag zog rau precipitates;
Quenching qhia txog kev ntxhov siab sab hauv- kev lag luam tsim nyog- tawm kom muaj zog tawm los; distortion tswj teeb meem rau precision qhov chaw.
Kauj Ruam 3-Txoj Kev Laus
Reheat ntawm txog175-190 degreerau kwv yees8-12 teev.
Fine Mg₂Si precipitates daim ntawv uniformly, zoo heev nce hardness thiab yield zog;
Kev laus lub sij hawm thiab qhov kub thiab txias sib npaug zog tiv thaiv elongation -tseem ceeb rau cov khoom precision.
Qhov tshwm sim thiab daim ntawv thov
Hom 6061-T6 yield ≈ 276 MPa, zoo qaug zog tsis kam, corrosion kuj thiab weldability (nrog lub zog rov qab ib WPS);
Daim ntaub ntawv: tsheb kauj vab thav duab, automotive qhov chaw, marine fittings, aerospace Cheebtsam, thiab structural thiab architectural seem.
Paub meej tias qhov kub thiab txias qhov tseem ceeb ntawm kev tswj hwm tus qauv (ASTM B209 / B221, EN 573/755) thiab daim ntawv pov thawj zeb.
