Lattice deformations in quasi-dynamic strain glass visualised and quantified by aberration corrected electron microscopy


  • In honour of Lee Tanner (1931–2013)


Advanced transmission electron microscopy and statistical parameter estimated quantification procedures were applied to study the room temperature quasi-dynamical strain glass state in Ni–Ti alloys. Nanosized strain pockets are visualised and the displacements of the atom columns are quantified. A comparison is made with conventional high-resolution transmission electron microscopy images of point defect induced strains in Ni–Al alloys. pssb201350351-gra-0001
