Abstract
We have investigated the behavior of nonconservative (100) antiphase boundaries in L-ordered alloys, close to the congruent first-order order-disorder transition. Very accurate inhomogeneous cluster-variation-method calculations in the tetrahedron approximation show that wetting does occur through an infinite series of layering transitions with average logarithmic divergences for the width of the wetting layer and for the excess entropy.
