Kev sib piv ntawm kev kho cua sov
7075-T6 Aluminium Thaum tshav kub kub kho
7075-T6 aluminium undergoes kev kho cua sov ua raws li kev laus kev laus. Thaum lub sij hawm kev kho cua sov, cov hlau yog rhuab mus rau kwv yees li 475-495 ° C thiab ces quenched sai heev kom yaj alloying ntsiab rau hauv lub txhuas matrix. Artificial aging yog tom qab ntawd ua, feem ntau ntawm qhov kub ntawm 120 thiab 150 ° C, txhawm rau txhim kho precipitate tsim thiab ua kom muaj zog txhua yam.
7075-T6511 Aluminium Thaum tshav kub kub kho
Ntxiv nrog rau kev kho cua sov thiab kev laus dag, 7075-T6511 txhuas yog raug rau cov txheej txheem kev ntxhov siab. Qhov no yog ua tiav los ntawm mechanically stretching cov khoom los txo cov kev ntxhov siab sab hauv tsim thaum tsim khoom. Tom qab stretching, cov khoom yog straightened los xyuas kom meej qhov ntev stability. Cov temper no feem ntau nkag rau hauv cov ntawv extruded lossis forged thiab zoo haum rau cov khoom siv loj dua.
