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 Σ5(013).

铝晶界孔形成的模拟

通过计算机模拟方法研究了在倾斜晶粒边界处[100]取向不良的孔隙形成的可能性。在400、500和600 K的温度下研究了三种普通类型的特殊晶界和三种晶界。结果表明，晶界空位和晶粒内3％晶格空位的存在不足以形成孔，而在存在6％晶格空位的情况下，仅在晶粒中形成孔。晶界上的孔是在500和600 K的温度下形成的，晶格空位浓度分别为4和5％。在特殊的晶界Σ5（013）上不会形成孔。
