Grain boundary character distribution, texture and superplastic deformation behavior of an Al-Li Alloy

摘要

The grain boundary character distribution and the texture of 2091 Al-Li alloy recrystallized at different temperatures were measured by TEM and X-ray techniques respectively. The occurrence frequency of low - energy boundaries decreases with increasing recrystallization temperature, while the frequency of high - energy boundaries increases. The strongest component of recrystallization texture in the test temperature range is {011} <111>.
