Cov ntsiab lus ntawm T Tempers rau 6061 & 7075 Aluminium Phaj
Txawm tias6061 thiab 7075 txhuas phajqhia tib cov tshuaj muaj pes tsawg leeg nyob rau hauv lawv cov tsev neeg alloy, sib txawv T tempers (T6, T651, T6511) feem ntau cuam tshuam:
Residual stress theem
Machining stability
Risk ntawm deformation
Flatness thiab qhov tseeb qhov tseeb
T651 thiab T6511 txhuas phaj muajqis zog sab hauvtshaj T6, ua rau lawv tsis tshua muaj kev sib tsoo thaum lub sij hawm CNC machining.
Aluminium Phaj "T" Temper Heat Treatment Process
Kauj Ruam 1: Kev kho cua sov & quenching
Aluminium phaj yog rhuab mus rau kwv yees li527 degreethiab tuav rau txog1 hnu. Qhov no dissolves alloying ntsiab (Mg, Si, Zn) rau hauv cov txhuas matrix.
Lub phaj yog cesquenched sai sai hauv dejtiv thaiv nag lossis daus ntxov ntxov.
Kauj Ruam 2: Kev Kho Kev Laus
Lub phaj yog reheated rau kwv yees li177 degreethiab tuav rau1-18 teev, nyob ntawm thickness thiab daim ntawv thov.
Cov kauj ruam no tsimMg₂Si dej nag, ho nce zog thiab hardness.
