- Title
The Sizes of Jumps and Levels of Deformation of Metals.

- Abstract
It is proposed to characterize levels of deformation by a size of its jumps, which can be observed when the strain rate is accurately measured in experiments with load that is constant or defined according a certain law. At the micro- and nanometer scales, the strain rate was measured and the deformation jumps were computed for copper, lead, and tin using a precision interferometric method. A correlation of the size of jumps with the Burgers vector of dislocations in metals was shown, and hypotheses about ensembles of dislocations participating in the formation of a deformation jump are made.
