      abstract     = {Although the precipitation and recrystallization of
                      Mg–Al–Ca–Mn based alloys have been well investigated
                      individually, there is still a lack of a detailed
                      investigation on the effect of the Al-rich clusters, Mn-rich
                      precipitates and/or Ca-rich Laves phases formed from dynamic
                      precipitation during rolling on the grain size and texture
                      as well as yield strength. Here, we have investigated the
                      effect of Mn (1 wt. $\%)$ on the dynamic precipitation and
                      yield strength of rolled Mg–3Al–1Ca alloy after rolling
                      up to 1 and 6 passes (at 350 °C and 300 °C). It was found
                      that an effective grain refinement can be obtained due to
                      the fact that the dynamic precipitation enhances dynamic
                      recrystallization by particle stimulated nucleation (PSN)
                      mechanism. No significant texture change was obtained
                      although the dynamic precipitation of Mn-rich particles due
                      to the addition of 1 wt. $\%$ Mn results in a change from an
                      RD-split texture to a strong basal texture. Three different
                      Mn-rich phases ((i) large primary Al8Mn5 phase, (ii) the
                      long plated-shaped Al8Mn5 phase, and (iii) nanoscale Al8Mn5
                      phase), C15 Laves phase (Al2Ca) and Al-rich clusters (G.P.
                      zone), were observed, while no plate-shaped Al–Ca
                      precipitate was observed on the basal plane of α-Mg matrix,
                      indicating a competition among the formation of Al-rich
                      clusters, plate-like Al–Ca precipitates, Ca-rich Laves
                      phase, and Mn–rich phase within α-Mg matrix. Dispersion
                      strengthening by the Ca-rich Laves phase, Mn–rich phase
                      and Al-rich clusters is proposed to be attributed to the
                      significant improvement of yield strength. This
                      investigation highlights the importance of elucidating the
                      effect of the dynamic precipitation on yield strength of
                      rolled Mg–3Al–1Ca–1Mn alloys and provides helpful
                      hints to further optimize the deformation and mechanical
                      properties of Mg–Al–Ca–Mn based alloys.},
