Simulation of the pore formation at grain boundaries in aluminum

Abstract:
The possibility of the pore formation at the tilt grain boundaries with the [100] misorientation axis is studied by computer simulation methods. Three special boundaries and three grain boundaries of a general type are studied at temperatures of 400, 500, and 600 K. It is shown that the presence of 3% lattice vacancies is insufficient for the pore formation both at the grain boundary and in grains, whereas in the presence of 6% lattice vacancies, pores are formed only in grains. Pores on grain boundaries are formed at temperatures of 500 and 600 K with a lattice vacancy concentration of 4 and 5%, respectively. Pores are not formed on a special grain boundary $\Sigma$5(013).
