The effect of lattice misfit on the mechanical properties of L12-strengthened medium-entropy alloys with low stacking fault energy

Journal of Materials Research and Technology
L12 precipitates reinforced face-centered cubic (FCC) high entropy alloys have attracted broad attention because of their good strengthening and ductility behaviors.

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.

Interplay of Strain Relaxation and Chemically Induced Diffusion Barriers: Nanostructure Formation in 2D Alloys [PDF]

, 2004
We study the formation of nanostructures with alternating stripes composed of bulk-immiscible adsorbates during submonolayer heteroepitaxy. We evaluate the influence of two mechanisms considered in the literature: (i) strain relaxation by alternating ...

Energetics and atomic mechanisms of dislocation nucleation in strained epitaxial layers [PDF]

, 2003
We study numerically the energetics and atomic mechanisms of misfit dislocation nucleation and stress relaxation in a two-dimensional atomistic model of strained epitaxial layers on a substrate with lattice misfit.

Partial decoupling between strain and polarization in mono-oriented Pb(Zr0.2Ti0.8)O3 thin film [PDF]

, 2007
The structural evolution of epitaxial mono-oriented (i.e. with the c-axis perpendicular to the interface) ferroelectric Pb(Zr0.2,Ti0.8)O3 thin film has been investigated, using high resolution, temperature dependent, X-ray diffraction.

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 ...

Development of Co–Ni–Al–V–Ta–Cr-based superalloys with high-temperature strength and excellent oxidation resistance

Journal of Materials Research and Technology, 2023
In this study, the effects of V on the microstructure, lattice misfit, solvus temperatures, and oxidation behaviors of the Co–Ni–Al–V–Ta-based superalloys are investigated.

Large bi-axial tensile strain effect in epitaxial BiFeO3 film grown on single crystal PrScO3

Scientific Reports, 2023
A BiFeO3 film is grown epitaxially on a PrScO3 single crystal substrate which imparts ~ 1.45% of biaxial tensile strain to BiFeO3 resulting from lattice misfit.

Misfit in Inconel-Type Superalloy

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.
