文摘
- •
Lattice preferred orientation is not strongly affected by recrystallisation.
- •
Ice crystal intrinsic anisotropy is transferred to the polycrystalline scale.
- •
LPOs and SPOs control strain hardening and subsequent softening.
- •
Strain localisation bands are masked by grain boundary migration.
- •
Masked strain localisation can be recognised from polar ice microstructures.
