| Abstract: | This paper researches the influence of beryllium on 7475Al alloy hardness time curve, recrystallization volumn percentage time curve and grain size by recrystallization annealing. It was found that the addition of a suitable amount beryllium can increase 7475Al alloy recrystallization temperature, reduce recrystallization speed, double the surface hardness, and make the grain refine effectivly at the same time. |
