Towards a dependable TEM characterization of hot-dip galvanized steels with low and high Si content

open access: yesMaterials & Design, 2023
Designing Advanced High-Strength Steels assumes fine-tuning of alloying elements to enhance performance properties. This affects the kinetics of Fe-Zn interaction during further galvannealing.

In situ TEM heating experiments on thin epitaxial GeSn layers: Modes of phase separation

open access: yesAPL Materials, 2023
The thermal stability of GeSn epitaxial thin films was investigated via in situ transmission electron microscopy (TEM). Samples were grown with a similar layer structure and 10 at.% Sn content by either molecular beam epitaxy or chemical vapor deposition.

Mechanisms of phase transformations in iron

open access: yesЛитьë и металлургия, 2022
Gibbs molar volumetric energy and iron boundary molar energy are determined depending on temperature. It has been shown that phase transformations in iron occur under thermodynamically equilibrium conditions.

Canonical and D-transformations in Theories with Constraints [PDF]

open access: yes, 1995
A class class of transformations in a super phase space (we call them D-transformations) is described, which play in theories with second-class constraints the role of ordinary canonical transformations in theories without constraints.Comment: 16 pages ...

Shape Memory Alloy Nanostructures With Coupled Dynamic Thermo-Mechanical Effects [PDF]

open access: yes, 2014
Employing the Ginzburg-Landau phase-field theory, a new coupled dynamic thermo-mechanical 3D model has been proposed for modeling the cubic-to-tetragonal martensitic transformations in shape memory alloy (SMA) nanostructures.

In-Situ Annealing and Hydrogen Irradiation of Defect-Enhanced Germanium Quantum Dot Light Sources on Silicon

open access: yesCrystals, 2020
While light-emitting nanostructures composed of group-IV materials fulfil the mandatory compatibility with CMOS-fabrication methods, factors such as the structural stability of the nanostructures upon thermal annealing, and the ensuing photoluminescence (
