Journal ArticleDOI
On the origin of planar slip in f.c.c. alloys
TL;DR: In this article, the origin of planar slip in single-phase and precipitation-hardened f.c. alloys is discussed in detail, and it is shown that pronounced short range order (SRO) or short range clustering (SRC) in solid solutions are the main reasons causing plan-ar slip.
Journal ArticleDOI
Martensitic phase transformations in nanocrystalline NiTi studied by TEM
TL;DR: In this article, it was shown that the density of the nuclei is a function of the HPT strain and determined together with the annealing temperature the grain size of the nanocrystals ranging from 5 to 350 nm.

TL;DR: In this article, the authors investigated the influence of the grain size on the energy barrier of the martensitic transformation in nanocrystalline NiTi by transmission electron microscopy (TEM).
Journal ArticleDOI
Quantitative local profile analysis of nanomaterials by electron diffraction
TL;DR: In this paper, a method yielding a quantitative profile analysis from electron diffraction is worked out and combined with the local information gained from transmission electron microscopy images; it is applicable to various nanomaterials.
Journal ArticleDOI
Martensitic transformation of NiTi nanocrystals embedded in an amorphous matrix
TL;DR: In this article, the influence of the size on the martensitic phase transformation of spherical NiTi nanocrystals embedded in an amorphous matrix was studied by transmission electron microscopy.
