Titanium (tsawg dua lossis sib npaug li 0.15%): Ua raws li cov nplej refiner, txhawb nqa cov qauv zoo thiab cov qauv zoo ib yam.
Manganese (tsawg dua lossis sib npaug li 0.15%): Txo qhov tsis zoo ntawm cov hlau los ntawm kev tsim cov txiaj ntsig dispersoids.
Lwm yam kab kawm (tsawg dua lossis sib npaug rau 0.05% txhua): Khaws nyob rau theem qis kom tiv thaiv embrittlement.
Aluminium (qhov sib npaug): Lub hauv paus hlau muab qhov ntom ntom thiab tag nrho cov qauv kev ntseeg siab.
3. 6061 T6 Aluminium Temper: Kho cua sov thiab Artificial Aging
T6 Kev kho cua sov txheej txheem rau 6061 Aluminium
CovT6 zogsawv cev rau qhov siab tshaj - lub zog ntawm 6061 txhuas thiab ua tiav los ntawm kev tswj ob- theem txheej txheem:
Kev kho cua sov
Lub alloy yog rhuab mus rau kwv yees li515-535 degreethiab tuav ntev txaus kom yaj tag nrho magnesium{0}}silicon tebchaw rau hauv ib homogeneous kua tov. Tam sim ntawd tom qab ntawd, cov dej nrawm nrawm kaw cov ntsiab lus ntawm qhov chaw, tiv thaiv nag lossis daus ntxov.
Artificial Aging
Cov khoom quenched yog tom qab hnub nyoog ntawm160-180 degreerau8-12 teev, tso cai rau Finely dispersed Mg₂Si precipitates rau daim ntawv. Cov precipitates obstructing dislocation motion, ho txhim kho lub zog thiab hardness tsis dhau poob ntawm ductility.
