41. The pileup of dislocations at grain boundaries is a hallmark mechanism of the Hall Petch relationship. 42. The dark lines in the sensitized microstructure are networks of chromium carbides formed along the grain boundaries . 43. The dislocations are then propagated into the lattice in the same manner as in grain boundary initiation. 44. The movement of grain boundaries ( HAGB ) has implications for recovery and the nucleation of recrystallization. 45. Diffusion processes caused by electromigration can be divided into grain boundary diffusion, bulk diffusion and surface diffusion. 46. He studied the details of faults and grain boundaries in metals, and developed theoretical models of them. 47. The lack of grain boundaries contribute to the high yield strength ( and thereby resilience ) exhibited. 48. A picture of grain boundaries for polysilicon. 49. Grain growth is the process of grain boundary motion and Ostwald ripening to increase the average grain size. 50. This also accounts for grain boundaries .
