From an examination of the tensile behavior of cz ly12 alloys under different temperature and strain rate , two kinds of deformation and intergranular fracture behaviors were observed that were opposite to the characteristic strain rate range in fine - grained superplasticity . the mechanisms are described as follows . the high ductility achieved at high strain rate is generally attributed to the dominant role of gbs accommodating mechanisms , which is considered as dislocation creep within grains controlled by subgrains 研究選用自然時效淬火態的ly12鋁合金,進行了一系列不同溫度和應變速率下的單軸拉伸試驗, 480下,觀察到與傳統細晶超塑性特征區間相反的行為:較高應變速率下,動態再結晶使晶粒細化,促進了晶界滑移,亞晶界控制的晶內位錯蠕變是晶界滑移的主要協調機制。
