Effect of Lattice Misfit on the Stability of the Misfit Layer Compound (SnS)1+xNbS2
CrystalsThe prototype misfit layer compound (SnS)1.17NbS2 consists alternatingly of a metallic triatomic NbS2 layer, in which Nb atoms are sandwiched by S atoms, and an insulating SnS double layer featuring a NaCl-type structure.

Role of Hf and Re on the lattice misfit between γ/γ′of Co-Ti-V superalloys
Journal of Aeronautical Materials, 2021 The relationship between γ′ phase morphology and γ/γ′ lattice misfit degree in Co-Ti-V superalloy with different Hf and Re contents was studied by observation of microstructure and X-ray diffraction analysis.

The Effect of Temperature and Mo Content on the Lattice Misfit of Model Ni-Based Superalloys
Metals, 2019 The lattice parameters and misfit of the γ and γ′ phases in a series of model quaternary Ni-based superalloys with and without Mo additions have been determined using neutron diffraction between room temperature and 700 °C.

Misfit Strain Accommodation in Epitaxial ABO3 Perovskites: Lattice Rotations and Lattice Modulations
Physical review B: Covering condensed matter and materials physics, 2010 We present a study of the lattice response to the compressive and tensile biaxial stress in La0.67Sr0.33MnO3 (LSMO) and SrRuO3 (SRO) thin films grown on a variety of single crystal substrates: SrTiO3, DyScO3, NdGaO3 and (La,Sr)(Al,Ta)O3. The results show, that in thin films under misfit strain, both SRO and LSMO lattices, which in bulk form have ...
