ROLE OF PERIODIC ANTIPHASE BOUNDARIES IN ORDER-DISORDER PHASE TRANSITION IN LONG-PERIOD SUPERSTRUCTURES

摘要

The main regularities of long-period superstructures, revealed by X-ray study, were considered. The temperature behavior of the characteristics of this class of superstructures was analyzed. It was shown that the character of the temperature change in the antiphase period affects the specific features of the order-disorder phase transition in alloys with long-period superstructures.
