利用 X 射线衍射技术测定了 Al-5Zn-2.3Mg-0.4Cu(LB733)铝合金的再结晶特性,发现其具有较高的再结晶温度(313℃);再结晶完成后,在较宽的温度范围(～100℃)内晶粒没有明显的聚集长大。
The recrystallization characteristics of Al-5Zn-2.3Mg-0.4Cu (LB733) aluminum alloy were measured by X-ray diffraction and found to have a high recrystallization temperature (313 ℃). After the recrystallization, Within the range (~ 100 ℃), there is no obvious aggregation and growth of grains.
