| Popis: | Beryllium is a metal having unique physicomechanical properties, including a record specific rigidity, but it undergoes cold and red brittleness. As a result of long-term investigations, we were the first to manufacture high-purity fine-grained beryllium, which has the room-temperature plasticity that is higher than that of commercial-purity powdered beryllium by an order of magnitude and exhibits superplastic flow at elevated temperatures. In this review, we summarize the results of the long-term study of the superplastic flow of beryllium and the mechanisms of high-temperature deformation. |
