Advanced TEM and SEM methods applied to 3D nano- and microstructural investigations of $Ni_{4}Ti_{3}$ precipitates in Ni-Ti (SMA) Universiteit Antwerpen
Two different kinds of experimental approaches yielding three-dimensional structural information on metastable semi-coherent precipitates are demonstrated. By combining high-resolution images from two independent viewing directions a full description of the strain field surrounding a nano-sized Ni4Ti3 precipitate in Ni-Ti can be obtained. The principal axes and strains correlate well with the transformation strain of the observed R-phase ...
