On the effects of the Mg content on the critical strain for the jerky flow of Al–Mg alloys
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2015 The jerky flow of Al–Mg alloys is investigated during tensile tests at imposed strain rate and room temperature. The strain and strain rate dependences of the magnitude of the stress drops, the range of plastic instability and the critical strain for the
