The thermomechanical conditions of open die forging of zirconium alloy ingots determined by rheological tests
The article reports the results of investigation into variations in the rheological properties of the Zr-1 % Nb alloy when deformed under the conditions of physical modelling of the process of multi-stage hot open die forging of ingots. The programme for rheological testing of the alloy was develope...
