Abstract

Polycrystalline samples of a Fe-Mn-Si-Cr-Ni shape memory alloy containing a 70% fraction of thermal [MATH]-martensite have been studied by H.R.E.M. Images taken along a [MATH] axis clearly show, at the atomic level, the layered substructure of larger [MATH]-bands. By analysing numerically processed images of elementary [MATH]-laminate tips, the [MATH] interface could be described by a periodic array of 30° and 90° Shockley partials in a 2:1 ratio, leading to self-accommodation of thermal [MATH]-martensite at the finest scale.
