- Under the careful retrospection and analysis on the previous and recent experiments about mechanical behavior of nanocrystalline metals performed by almost main investigators , the dislocation and atomic diffusion is believed to contribute hardly to the deformation of nanocrystalline alloy , and a model based on thermal activation process was applied to fit the experimental data of nanocrystalline ag
结果表明，纳米晶金属ag的不仅具有比粗晶ag高2 - 6倍的拉伸和压缩强度，而且在大范性形变阶段显示了极低的加工硬化和应变速率敏感性。结合位错理路和非晶合金形变特征，提出纳米晶金属ag的塑性变形主要由于晶界滑移贡献。 - But in fact , teacher movement of middle school has lost clearly regulations in vast countryside of developing area . it has affected seriously the stability of the teachers of this area , made many teachers leave and the education worse and worse
