dislocation mobility in a sentence

1. The ordered structure exhibits superior elevated-temperature properties because of the long-range ordered superlattice, which reduces dislocation mobility and diffusion processes at elevated temperatures.
2. Pinning points, or locations in the crystal that oppose the motion of dislocations, can be introduced into the lattice to reduce dislocation mobility, thereby increasing mechanical strength.
3. It's difficult to find dislocation mobility in a sentence.
