abstract = {Texture modification during sheet rolling appears
differently in binary Mg-RE (rare-earth) or Mg-Ca alloy,
compared to their ternary counterparts containing Zn. The
differences in texture development and the active
deformation mechanisms under tensile loading were
investigated in the binary alloys. These analyses are based
on in-situ synchrotron experiments and electron backscatter
diffraction measurements to reveal direct experimental
evidence of the texture development and the active
deformation mechanisms. Higher activations of nonbasal < a >
and pyramidal < c+a > dislocations were found in the Nd or
Ca containing Mg alloys, compared to the Mg-Zn alloy. The
texture development shows an obvious feature, which is a
broadening of the basal pole intensity distribution
perpendicular to the loading direction and a strengthening
of the <1010> pole at the loading direction in all examined
sheets. This texture development relates to the higher
activation of prismatic < a > slip. The addition of Zn in
the Mg-RE or Mg-Ca alloys further promotes the activation of
nonbasal < a > and pyramidal < c+a > dislocations. This
enhanced prismatic < a > slip in the Zn containing ternary
alloys is confirmed by EBSD misorientation analysis.},
