Evolution of dislocation cells during plastic deformation ZHOU Zhi-min(周志敏)1, SUN Yan-rui(孙艳蕊)1, ZHOU Hai-tao(周海涛)2 (1. College of Science, Northeastern University, Shenyang 110004, China; 2... understood. It is still an unsolved question whether or not finer grain sizes down to 100nm could be reached. A semi-quantitative model for the evolution of dislocation cells in plastic deformation......

data to constrain the fault slip distribution of the L’Aquila earthquake. INGV also gave a solution for the focal mechanism. But all of them used the dislocation model in an isotropic homogeneous half..., the fault geometric parameters were determined using non-linear inversion method based on the model of rectangular dislocation in a homogeneous elastic half space. Secondly, the details of fault slip......
are transformed into with small angle by dislocation slip. And in the nanometer crystalline grain layer, subgrain are transformed into randomly oriented equiaxed nanograins. Key words: titanium alloy; high energy shot peening; nanograin; twin; dislocation slip 纳米材料由于晶粒细小,界面......

, and the dislocation density on non basal plane is much higher than that of 45? sample (Fig.7(b)). Therefore, basal slip is the main deformation mechanism for 45? sample, while non basal slip is the main... level at a strain of 0.3% for different oriented samples. Since not much twin platelets can be seen during plastic deformation for 45? and 0? samples according to OM analysis and dislocation slip......
