A similar effect is seen with 3BAl, in this case after 2 hours the grain size could not be measured due to the presence of feather crystals. Results for 6TiAl are not shown because all samples showed feather crystals.

Reference: a fan-shaped columnar structure, referred to as “feather crystals”

Reference information:
The aluminum alloy ingots cast without grain refiner often exhibit a fan-shaped columnar structure, referred to as “feather crystals” (Ref4). This structure, illustrated in Fig. 10, may be found in low- and high-solute alloys. It is most likely to develop when there is a steep thermal gradient ahead of the solidifying interface (Ref5) or an inadequate addition of grain refiner (Ref10). At higher magnification, the feather crystals consist of twinned columnar grains (Fig. 11)
