Research on Corrosion Under Tension a Aluminum Alloy AlZn5.7MgCu

Abstract

The paper presents the results of the research on the resistance to stress corrosion on some samples from the alloy. AlZn5.7MgCu which were previously subjected to various thermal and thermomechanical processing. The gravimetric index or corrosion rate Vcr was used to evaluate the corrosion resistance under tension of the samples investigated in this regard.
