Role of ordering energy in formation of grain structure and special boundaries spectrum in ordered alloys with L12 superstructure

It was revealed that an average energy of special boundaries is proportional to APB energy in the alloys with L12 superstructure. This fact proves the appearance of GAPBs in the plane sites of special boundaries in coincidence with ordered alloys. It was determined that the more energy of special boundaries in ordered alloys, the more energy of complex stacking fault. There is a correlation between the distribution of special boundaries as a function of relative energy and ordering energy: the more ordering energy, the more degree of washed away of distribution. The correlation between averaged relative energy of special boundaries and ordering energy was detected: the more ordering energy, the more average energy of special boundaries. The reverse relation between ordering energy and average number of special boundaries in grains limited by boundaries of general type was discovered.
