Abstract
A stress-deformed state of zirconium alloy in a cold rolling site is investigated considering the process of evolution of localized deformation autowaves and changes in the ultrasound velocity. It is established that transition from the upsetting to reduction region is accompanied by significant exhaustion of the plasticity margin of the material; therefore, fracture of the material is most probable exactly in this region. It is stated that traditional methods of estimating the plasticity margin from the mechanical characteristics cannot reveal this region; comprehensive analysis of plastic strain macrolocalization and results of acoustic measurements are required.
