A: Lub zog ntawm 6061 T6 tso siab rau Mg₂Si precipitates. Thaum qhov kub siab tshaj li ntawm 150 degree, cov precipitates no pib coarsen los yog yaj, ua rau muaj kev poob qis hauv lub zog. Yog li ntawd, 6061 T6 feem ntau tsis pom zoo rau kev siv cov qauv uas qhov ntev - qhov kev pabcuam kub siab tshaj 150℃.
