Quantitative assessment of the influence of the Portevin-Le Chatelier effect on the flow stress in precipitation hardening AlMgScZr alloys

Portevin-Le Chatelier (PLC) effect often occurs in many alloy systems and leads to flow stress variations. When precipitation occurs, the PLC behavior changes and its resultant influence on the flow stress becomes more complicated, which has not yet been clarified. The well-known interaction mechani...
