Study of point defects for B2 structures with a ω-type martensitic phase

The molecular dynamics method has been used to study the effects of the inheritance from point defects in B2 structures having an ω-like martensitic transformation with different final reaction products. For order defects, antistructural atoms, and their simplest complexes it has been shown that in several cases the number of atoms in the defects increases sharply for martensite during the transition to austenite. Here the fraction of chemical energy accumulated by the defects grows. A certain type of defect in the B2 structure in martensite corresponds to the appearance of high-energy linear disordered chains in directions of the [111]B2 type. This can play a substantial role in the determine the path of the reverse martensitic transformation.
