摘要：
We present quantitative estimates of the local lattice distortion ("deformational") contribution to the configurational interactions in disordered substitutional alloys which determine their ordering, segregation and related phenomena. We show that, unlike to a widespread opinion, the deformational terms are often quite large, thus taking them into consideration is necessary for the quantitative theories of these alloys.
