SIMULATION OF FLOW STRESS OF SINGLE-PHASE ALUMINUM ALLOYS OF THE Al-Mg, Al-Cu AND Al-Zn SYSTEMS IN THE PROCESS OF HOT DEFORMATION

摘要

Curves of flow of alloys of the Al - Mg, Al - Zn and Al - Cu systems are obtained for the temperature range of 200 - 500℃ at deformation rates from 0.1 to 30 sec~ '. A mathematical model of the dependence of the flow stress of the alloys on the temperature and rate parameters of the deformation is designed, which makes it possible to compute flow stresses with an error of 5%.
