Kev kho cua sov thiab kev ua haujlwm sib txawv
7075-T651
Qhov no temper undergoeskev kho cua sov, tswj kev ntxhov siab, thiab kev laus dag. Kev ntxhov siab yog ua tiav los ntawmnruab nrab stretching, uas txo cov residual kev nyuaj siab thaum tuavzoo ductility. Raws li qhov tshwm sim, 7075-T651 ua tau zoo hauv cov ntawv thov cuam tshuam nrog deformation, vibration, lossis cuam tshuam.
