  1. The apparent activation volume calculated by the model is about 2500a3, which was ten times larger than that of usual amorphous alloy and was at the same range of the amorphous polymer. the model shows the main deformation mechanism of nanocrystalline ag is grain boundary sliding, which in some extent declares the similar forms of equation with amorphous alloys. with the ananlysis to the hrem of nanocrystalline ag, the discrepancy of the apparent activation volume between the nanocrystalline ag and amorphous alloys is interpreted by the loss of atoms participating in grain boundary sliding without enough reconstruction by the movement of atoms under the low temperature

    運用晶界滑移的熱激活理論對壓縮實驗結果進行了數值擬合,擬合曲線與實驗數據符合很好,得到了晶界滑移的表觀激活體積(熱激活基本單位體積與局域瞬態應變的乘積) ,約為2500a ~ 3 ,先當于幾十個原子體積大小的瞬態變化,約為非晶合金的10倍以上,與非晶高聚物的表觀激活體積相當。
  2. The substructure near the damage position was studied by ebsp, then vonbined with the relationship among substructure grain boundary sliding grain size and material deformation compatibility the mechanics of creep damage was discussed

    使用電子背散射衍射技術研究了不同損傷位置附近的亞結構形成情況,結合亞結構、晶界滑移、晶粒尺寸與材料變形協調性等材料變形特點,對蠕變損傷機理進行了探討。
