摘要: Serration flow is first observed in a fine-grained Mg-0.8 wt pct Ca alloy throughout the deformation history. Strain rate sensitivity (SRS) sensitive with temperatures. A positive SRS combination type of downward serration found at low temperatures, which mostly attributed to strong dislocation–dislocation interaction. However, high another upward and changed negative as result solute pinning dislocation.
