Mechanical behavior of nanostuctured al-6082 alloy processed by equal channel angular pressing (ecap)‎ technique

Abstract EN

In this paper the mechanical behavior of nanostructured Al-6082 alloy material has been investigated by using the upsetting test.

The material of specimens was produced by the ECAP technique and the specimens were taken out from the three perpendicular axis of ECAP part.

The tests were carried out using an electro-mechanic testing machine at room temperature to avoid recrystallization of the nanostructure, and the speed of the clamping head was 2 mm / min.

The flow curves were plotted for all specimens in the three directions.

A computer program was used to analyze the flow curve data to determine the stress and strain parameters, by plotting the fit curves on the flow curves.

Ludwik ductile criteria equation was applied in this program to plot fitting curves lines.

The deformed specimens clearly show the anisotropic behavior.
