  1. 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徵區間相反的行為：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。
  2. Fine grained fracture

    細晶斷口
