Hauv kev nrhiav kev ua haujlwm zoo ntawm cov qauv, qhov twg txhua gram thiab txhua megapascal suav, ib qho txhuas alloy sawv cev rau tus yeej tsis muaj kev sib cav ntawm lub zog: 7075. Thaum cov hlau no raug forged precision thiab coj mus rau tempered T652, ib qho specification xav tau cov qib siab tshaj plaws ntawm kev lees paub sib xws, nws hloov mus ua cov khoom siv ntawm lub peev xwm tshwj xeeb. Raws li koj tus khub muab khoom thiab machining mob siab rau, peb nthuav qhia qhov kev sib sib zog nqus tob tob rau hauv7075-T652 forged txhuas phaj, piav qhia vim li cas nws tseem yog qhov kev daws teeb meem tseem ceeb thaum qhov ua tsis tiav tsis yog qhov kev xaiv

1. Kev rhuav tshem cov hlau nplaum: Lub zog hlau uas tsav los ntawm zinc

7075 yog ib feem ntawm lub zog siab heev 7000 series (Al-Zn-Mg-Cu). Nws cov khoom muaj zog tsis yog qhov xwm txheej tab sis tau tsim los ntawm kev sib koom ua ke ntawm cov ntsiab lus tseem ceeb thiab cov txheej txheem thermomechanical tswj hwm zoo.

Zinc (Zn): 5.1% ~ 6.1% - Lub hauv paus ntawm 7075 lub zog. Zinc, ua ke nrog magnesium tsim cov ntom ntom, sib xws η' (MgZn₂) thiab T (AlZnMgCu) precipitates thaum laus. Lub tshuab ua kom tawv nqaij no muab cov alloy lub zog-rau-qhov hnyav piv tsis tau sib piv.

Magnesium (Mg): 2.1% ~ 2.9% - Ua haujlwm sib koom tes nrog zinc los tsim cov theem txhawb zog tseem ceeb. Magnesium kuj tseem ua rau cov hlau teb rau kev kho cua sov thiab kev ntxhov siab corrosion cracking tiv thaiv thaum ua tiav zoo.

Tooj Liab (Cu): 1.2% ~ 2.0% - Ua kom muaj zog ntxiv los ntawm kev ua kom cov kua khov kho thiab los ntawm kev koom nrog hauv kev tsim cov av qeeg. Tooj liab ua rau muaj kev tiv thaiv kev qaug zog thiab kev tawv, txawm tias muaj kev pauv pauv hauv kev tiv thaiv kev xeb dav dav, uas xav tau cov txheej tiv thaiv hauv ntau daim ntawv thov.

Chromium (Cr): 0.18% ~ 0.28% - Ib qho tseem ceeb ntawm cov khoom siv ua kom cov noob qoob loo thiab cov tshuaj tiv thaiv recrystallization. Chromium tsim cov dispersoids zoo uas khi cov ciam teb ntawm cov noob qoob loo, ua rau cov noob qoob loo zoo dua, sib npaug zoo dua, tshwj xeeb tshaj yog qhov tseem ceeb hauv cov khoom forged uas txhim kho kev tawv thiab tiv taus kev ntxhov siab-xeb tawg (SCC).

Lub T652 Temper Designation yog tshwj xeeb thiab xav tau:

T6: Cov tshuaj tau kho cua sov, quenched, thiab artificially aged kom txog thaum lub zog siab tshaj plaws.

T652: Qhia tias cov khoom siv tau dhau los ntawm kev tswj hwm kev ntxhov siab ntxiv tom qab kev kho cua sov (los ntawm kev ncab lossis nias) thiab ua ntej kev laus kawg. Cov txheej txheem no, feem ntau siv rau cov phaj hnyav, txo cov kev ntxhov siab quenching seem, yog li txhim kho qhov ruaj khov thaum lub sijhawm machining thiab txhim kho kev tiv thaiv rau kev ntxhov siab-xeb tawg hauv qhov kev taw qhia luv luv. Qhov no ua rau 7075-T652 forged phaj txhim khu kev qha rau cov khoom sib xyaw, siab-precision.

2. Kev Ntsuas Qhov Zoo Tshaj Plaws: Cov Qauv Ntsuas Khoom Siv Kho Tshuab & Lub Cev

Lub7075-T652 phaj forgedmuab cov qauv vaj tse uas txhais tau tias qib siab ntawm kev ua tau zoo ntawm txhuas, ua ke cov txiaj ntsig isotropic ntawm kev forging nrog kev ruaj khov ntawm T652 temper.

Cov Khoom Siv Kho Tshuab Ib Txwm Muaj (Ib AMS 4136 / ASTM B209):
