Abstract

The article contains experimentally obtained dependencies that by common usage permit to predict the mechanical properties of the metal as after a cycle of cold pilger rolling, and along the length of the deformation zone. These dependencies link specific strain parameters to found criterion of changes in mechanical properties. The final dependences and technique for predicting of changes of the properties were experimentally verified.
