Transmission electron microscopic observations, and crystallographic analyses, suggested that the only significant reported observation of {112} pseudo-twins in B2 structures (Goo et alia, 1985) was, in fact, a mis-identification of {114} true twins.

Is the Observation of {112} Pseudotwins in the B2 Phase of Ni-Ti-Fe Shape-Memory Alloys a Case of Misidentification?. M.Krishnan, B.C.Maji: Philosophical Magazine Letters, 2001, 81[4], 243-9
