Discontinuous flow in Cu-2Be at various strain rates

Homogenized Cu-2 wt.% Be-0.3 wt.% Co wires of different diameters, D, show in a tensile test in a He bath at a strain rate of 5 × 10 −3 s −1 regular stress serrations. By increasing the strain rate above a characteristic value (varying nearly as D −0.5) the regular serrations change gradually to ext...
