Strain Hardening of 1565ch, AMg6, 01570, and 1580 Aluminum Alloys in the Process of Cold Rolling of Plates

Abstract

We study the phenomenon of strain hardening of 1565ch and AMg6 aluminum alloys of the Al – Mg system with high magnesium contents and 01570 and 1580 alloys with additions of scandium in the process of cold rolling of plates. We plot hardening curves approximated by the well-known empirical expressions in the form of power functions constructed with an accuracy sufficient for the engineering calculations of the characteristics of strength within the range of total relative compressions 0 – 35%. It was shown that, in the alloys alloyed with scandium, the phenomenon of hardening observed in the course of cold rolling is weaker than in alloys without scandium.
