Analysis of rheological behavior of AL-CU-MG-FE-NI alloy at elevated temperatures using phenomenological flow stress model
Source abstract
Abstract
The aim of this paper is to predict accurately the flow stress of Al-Cu-Mg-Fe-Ni alloy at temperatures of the range 350–470°C with the help of flow stress mathematical model that is based on the phenomenological approach. This model includes both hardening and softening processes which follow the deformation of aluminium alloy A92648 at temperatures from 350°C to 470°C and strain rates of 0.001-0.4 s-1.
