Crystals, 2019 It has been a long-standing topic how the lattice misfit is cancelled at a semi-coherent interphase boundary consisting of terraces and steps. Apart from a set of misfit dislocations separating the coherent patches, the role of steps (which is frequently

Effect of Y and Mg on the Solidification Structure of Fe-36Ni Invar Alloy
High Temperature Materials and Processes, 2014 The effect of Y and Mg on the solidification structure of Fe-36Ni invar alloy melted in a carbon tube furnace was investigated using digital camera, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The results showed that Y or

Advanced Engineering Materials, EarlyView.Additive manufacturing introduces pronounced microstructural and crystallographic anisotropy in Ni‐based superalloys, resulting in orientation‐dependent creep deformation and damage. This review identifies the key microstructural origins of creep anisotropy, examines their influence on dominant deformation mechanisms, and highlights processing ...

Lattice Misfit of High Refractory Ruthenium Containing Nickel-Base Superalloys
, 2011 The influence of Ru, Co, Mo and W on the lattice misfit of eight highly alloyed Re containing single crystal nickel-base superalloys was investigated. High resolution X-ray diffraction (XRD) was used to relate the elemental partitioning behavior and the ...

Exceptional Electro‐Optic Coefficient Unlocked via Polarization Swaying in KNbO3 Thin Films
Advanced Functional Materials, EarlyView.We present the largest reported electro‐optic response in any material to date, guided by a new design principle that exploits ultralow coercive field polarization swaying enabled by low‐symmetry ferroelectric phases in monoclinic KNbO3 thin films for energy‐efficient classical and quantum photonic integrated circuits. ABSTRACT The electro‐optic effect

Two-dimensional and tubular structures of misfit compounds: Structural and electronic properties
Beilstein Journal of Nanotechnology, 2014 Misfit layer compounds are structures that consist of two sublattices differing in at least one of their lattice constants. The two different layers are stacked either an alternating or in a more complex series resulting in mono- or multi-layer misfit ...
