Mechanical of beryllium deformation and hardening at cold rolling

Beryllium rolling has been made on DUO-80 mills and quarto 15-35 with reductions of 0.2-1.0% for the run. A mechanism of beryllium deformation at cold rolling is determined by dislocations interaction with additive inclusions. The fracture of inclusion with microcracks formations is possible during deformation. At cold rolling of beryllium it is necessary to control the value of tensile stress in the metal to prevent the propagation of microcracks formed during inclusons cutting
