Specific values of D–D strain‐induced (elastic) interaction energy are used to analyze the unusual structure of the ordered solid solution Lu–D. Formation of the chains of interstitial atoms is due to both electronic and elastic interaction of the interstitials. At the same time, the main reason for the chain‐pair formation is the strain‐induced long‐range elastic interaction. Pairs of chains in antiphase are more advantageous than pairs of chains in phase from energy considerations. (© 2003 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
