What is the Difference Between Annealing Twins and ...

Sep 29, 2021· The key difference between annealing twins and deformation twins is that annealing twins form as a result of a change in the crystal system during cooling, whereas deformation twins form as a result of the stress on the crystal after the crystal has formed.. Crystal twinning is the sharing of some of the same crystal lattice points in a symmetric manner between two separate crystals.
