For cold rolling the strain hardening of aluminium alloys is an important aspect in processing control and sheet properties (see Chapter 11 of this book). For (technically) pure aluminium and some typical non-heat treatable Al-Mg-Mn sheet alloys, the flow stress evolution (i.e. strain hardening) is shown in Fig. 23.10 as function of cold rolling strain up to high rolling strains (90% reduction).
