Planar Defects and their Role in Physics-Mechanical Properties of Ordered Alloys and Intermetallides
Ordered alloys and intermetallides are important constructional materials, because they have a unique property – positive temperature dependence of yield stress. It is known that antiphase boundaries and washing effects of order, structures and concentrations of components near the boundaries are of great impotence in the appearance of positive temperature dependence. But superstructures have not only APB but also APB tubes, APB stripes. Their role is also important in physical and physics-mechanical properties of ordered alloys and intermetallides. The paper presents the classification of all the types of planar defects and their local properties for some alloys of different superstructure types.
