It is shown that pronounced short range order (SRO) or short range clustering (SRC) in solid solutions are the main reasons causing planar slip. Since the leading dislocations destroy SRO (SRC), glide plane softening occurs; therefore, a ... " - Twofold planar ambiguity

Ambiguity is generally taken to be a property enjoyed by signs that bear multiple (legitimate) interpretations in a language or, more generally, some system of signs. ’legitimate’ is a cover term I’m using to nod to the fact that many signs can, in principle, bear just about any interpretation.
