Misfit in Inconel-Type Superalloy [PDF]

Advances in Materials Science and Engineering, 2013
An important parameter for the characterization of microstructural changes in nickel base superalloys is the misfit - the relative difference between lattice parameters of γ matrix and γ′ precipitates.

Effects of lattice misfit of γ/γ′ phases on hydrogen embrittlement behavior in Ni-based single crystal superalloy

Journal of Materials Research and Technology
The effect of γ/γ′ phase lattice misfit on hydrogen embrittlement (HE) behavior was fundamentally investigated by utilizing a Ni-based single crystal CMSX-4 superalloy with a simple microstructure that can exclude the H-trapping effects of grain boundary,

Heterogeneous Nucleation Mechanisms in Systems with Large Lattice Misfit Demonstrated by the Pb(l)/Cu(s) System

Metals, 2022
Our current understanding of heterogeneous nucleation has been largely confined to the classical nucleation theory (CNT) that was postulated over 100 years ago based on a thermodynamic approach.

Improved Deformability of Co‐Free Medium Entropy Oxides by Controlled Entropy Destabilization [PDF]

Advanced Science, EarlyView.
Controlled entropy destabilization activates defect‐mediated plasticity in Co‐free (CuMgNiZn)O by promoting pre‐existing Cu‐rich secondary phases that serve as defect sources. Temperature‐dependent dislocation activity evolves from limited motion at room temperature to extensive glide and stacking‐fault formation at 600 °C, enabling improved plasticity

Effects of Lattice Misfit on the Growth of Coordination Polymer Heterostructures

Chemistry of Materials, 2015
The heterogeneous growth of a series of Prussian blue analogues on nickel hexacyanocobaltate seeds to produce coordination polymer heterostructues was investigated to determine the influence of lattice misfit over the growth mode. For small lattice misfits, the observation of a core–shell morphology indicates the growth of a pseudomorphic layer while ...

Lattice Misfit Strain as Origin for Biquadratic Interlayer Coupling [PDF]

Acta Physica Polonica A, 1996
The direct observations of some MBE grown superlattices show large interfacial undulations, which is attributed to the elastic relaxation of tensile . layers. Assuming that the interface lateral lattice deformation, due to ionic radii misfit, is given by the periodic solution of the Frenkel-Kontorova model, we calculate the magnetoelastic contribution ...

Cooperative dissociations of misfit dislocations at bimetal interfaces

APL Materials, 2016
Using atomistic simulations, several semi-coherent cube-on-cube bimetal interfaces are comparatively investigated to unravel the combined effect of the character of misfit dislocations, the stacking fault energy difference between bimetal pairs, and ...

A molecular dynamics study of heterogeneous nucleation in generic liquid/substrate systems with positive lattice misfit [PDF]

Materials Research Express, 2020
Nucleation plays a critical role in many natural and technological processes, and nucleation control requires detailed understanding of nucleation process at atomic level.

The Effect of Lattice Misfit on Deformation Mechanisms at High Temperature [PDF]

Advanced Materials Research, 2011
Understanding the relationship between deformation mechanisms and microstructure is essential if one wants to fully exploit the potential of advanced nickel base superalloys and develop future alloys. In the present work, the influence of the lattice misfit between  and ’ has been studied by means of in-situ loading experiments using neutron ...
