摘要：

The effect of average grain size on the mechanisms of polycrystal deformation are considered in the range of grain sizes from 1nm to 1cm. Critical grain sizes are selected. The activity of dislocation and diffusion mechanisms is analyzed. The deformation distribution in grains of different sizes is considered for a polycrystal as a whole within the grain size distribution. © Allerton Press, Inc. 2009.
