PLASTOMETRIC MODELLING OF THE FORGING PROCESS OF ZIRCONIUM ALLOY Zr-Nb BLANKS

摘要

The results of plastometric tests of Zr-1 % Nb alloy in the conditions of continuous and discrete loading using "Gleeble-3800" are presented. The tests were used for modelling hot forging of blanks in hydraulic press. The effect of thermome-chanical parameters on the level and form of the flow curves for the studied alloy in T = 700+900 °C and ε = 0.1-1.0 s~(-1) ranges was determined.
