7075-T651 thiab 7075-T6 yog ob qhov sib txawv temper designations for aluminium alloy 7075. Cov temper designations no qhia txog cov txheej txheem kev kho cua sov tshwj xeeb uas aluminium undergoes, ua rau cov khoom sib txawv thiab cov yam ntxwv. Ntawm no yog ib qho kev sib cais ntawm qhov sib txawv ntawm7075-T651thiab7075-T6:
Kev kho cua sov:
7075-T651:Qhov kev kub ntxhov no suav nrog kev kho cua sov, uas yog txheej txheem ntawm cov cua sov ntawm txhuas mus rau qhov kub thiab txias kom yaj cov ntsiab lus alloying, ua raws li cov kauj ruam quenching kom txias sai. Tom qab quenching, nws yog artificially hnub nyoog kom ua tiav cov yam xav tau txhua yam khoom.
7075-T6:T6 temper kuj suav nrog kev kho cua sov thiab quenching kauj ruam, tab sis qhov sib txawv nyob rau hauv cov txheej txheem kev laus. Nyob rau hauv T6 temper, cov txhuas muaj hnub nyoog ntawm qhov kub siab tshaj nyob rau hauv T651 temper. Qhov no ua rau muaj qhov sib txawv me ntsis ntawm cov khoom siv kho tshuab.
Mechanical Properties:
7075-T651:T651 temper muab lub zog siab thiab ua haujlwm zoo rau kev ntxhov siab corrosion tawg. Nws yog tus cwj pwm los ntawm lub zog qis dua piv rau T6 tab sis zoo dua toughness thiab kev nyuaj siab corrosion kuj.
7075-T6:T6 temper muaj lub zog siab tshaj plaws ntawm ntau yam tempers ntawm 7075 txhuas. Nws muaj lub zog ntau zog thiab tensile zog piv rauT651, ua rau nws zoo tagnrho rau cov ntawv thov uas yuav tsum muaj lub zog siab tshaj plaws.
Daim ntawv thov:
7075-T651:Qhov npau taws no feem ntau xaiv thaum qhov sib npaug ntawm lub zog thiab lub zog yuav tsum tau ua. Nws yog feem ntau siv nyob rau hauv daim ntawv thov xws li aerospace Cheebtsam, qhov uas tiv thaiv kev nyuaj siab corrosion cracking yog ib qho tseem ceeb heev.
7075-T6: T6yog xaiv rau cov ntawv thov uas xav tau lub zog siab tshaj plaws ntawm 7075 txhuas. Nws yog siv nyob rau hauv high-kev ua tau zoo aerospace qauv, kev siv tub rog, thiab high-stress Cheebtsam nyob rau hauv ntau yam industries.
Machineability:
Tus nqi:
7075-T651:T651 npau taws, nrog nws lub zog qis me ntsis, tej zaum yuav raug nqi ntau dua hauv qee qhov kev siv uas tsis tas yuav muaj lub zog siab tshaj plaws.
7075-T6:T6 temper, yog qhov kev xaiv muaj zog tshaj plaws, tej zaum yuav kim dua vim cov txheej txheem ua haujlwm ntxiv koom nrog.
7075-T651:Vim nws lub zog qis dua, T651 txhuas yuav yooj yim dua rau tshuab piv rau T6. Txawm li cas los xij, ob qho tib si temper designs feem ntau suav hais tias muaj kev ua haujlwm zoo rau aluminium alloys.
