Abstract
It is shown that the double-honeycomb textures observed in -Ta have an anomalous elastic compliance due to the change in relative size of different orthorhombic domains. The restoring force against this change is proportional to the domain-wall, or partial discommensuration, energy and tends to zero as the commensurate-incommensurate transition is approached giving a divergent contribution to the elastic compliance—an effect observed by Barmatz, Testardi, and di Salvo some years ago.
