“…A so-called RE texture was obtained in binary Mg-Ca alloy (Ca = 0.5 and 1.0 wt.%) after extrusion at 200 and 250°C, which was explained by the dynamic strain aging resulting from dislocation pinning by Ca [63]. A similar effect of Ca addition has also been seen in other alloys, like Mg-Zn-Ca alloy [64][65][66], Mg-AlCa alloy [64,67] and AZ31 [68]. A non-negligible amount of soluble Ca can remain in the hcp Mg in these alloys at high temperatures between 300 and 500°C.…”

“…Corresponding to this, it was found that Ca additions to MgZn alloys lead to textures that have strong similarities with those of rare earth elements containing Mg-Zn sheets [5,22]. In these works a strong contribution of different twin types and subsequent static recrystallisation are emphasised as texture determining mechanisms.…”

Rolling experiments were carried out on a ternary Mg-Zn-Ca alloy and its modification with zirconium. Short time annealing of as-rolled sheets is used to reveal the microstructure and texture development. The texture of the as-rolled sheets can be characterised by basal pole figures with split peak towards the rolling direction (RD) and a broad transverse angular spread of basal planes towards the transverse direction (TD). During annealing the RD split peaks as well as orientations in the sheet plane vanish whereas the distribution of orientations tilted towards the TD remains. It is shown in EBSD measurements that during rolling bands of twin containing structures form. During subsequent annealing basal orientations close to the sheet plane vanish based on a grain nucleation and growth mechanism of recrystallisation. Orientations with tilt towards the TD remain in grains that do not undergo such a mechanism. The addition of Zr delays texture weakening.

“…While it has been 43 established that dilute additions of Ca or rare earth (RE) solutes 44 can lead to a weakened basal texture after recrystallisation 45 [14][15][16][17][18][19], it is still controversial whether such alloying additions 46 can result in a weakened basal texture in the as-cold-rolled state 47 [17][18][19][20]. It is also unclear how the Ca alloying addition affects tex-48 ture evolution during the cold rolling process, primarily due to the 49 lack of direct observations of the texture evolution.…”
