  (E) As dislocation density increases, the resistance to dislocation movement increases. (F)

(E) As dislocation density increases, the resistance to dislocation movement increases. (F) As a metal is strain hardened, its ductility decreases. (G) A brittle material typically exhibits substantial plastic deformation with high energy absorption before fracture. (H) Ductile fracture is usually associated with intergranular and transgranular crack propagation mechanisms.
