We observed the high-speed anisotropic motion of an individual gold nanoparticle in 3D at the picometer scale using a high-energy electron probe. Diffracted electron tracking (DET) using the electron back-scattered diffraction (EBSD) patterns of labeled nanoparticles under wet-SEM allowed us to super-accurately measure the time-resolved 3D motion of individual nanoparticles in aqueous condition...

In this study, laser powder bed fusion (LPBF) was used for the fabrication of an interstitial-strengthened high entropy alloy (iHEA), Fe 49.5 Mn 30 Co 10 Cr C 0.5 (at.%). The as-fabricated iHEA possesses excellent strength-ductility synergy during tensile loading, with fracture strength reaching up to 1109 MPa at 37% engineering strain. Electron backscatter diffraction (EBSD) and energy synchro...

Understanding the local fracture resistance of microstructural features, such as brittle inclusions, coatings, and interfaces, at microscale is critical for microstructure-informed design materials. In this study, a novel approach has been formulated to decompose J-integral evaluation elastic energy release rate three-dimensional stress intensity factors directly from experimental measurements ...

This paper presents a methodology to define and quantify the level of work hardening locally in material. The is proposed after thorough experimental study based on three complementary techniques for microstructural characterizations: microhardness, X-ray diffraction (XRD) Electron Backscatter Diffraction (EBSD) applied Inconel 718 samples. In our analysis, several loading histories including s...

This paper evaluates the suitability of X-ray diffraction (XRD) technique to characterize phase transformation during metal forming metastable austenitic steel AISI 304L. Due plastic deformation, from γ-austenite into α′-martensite occurs. The XRD peaks at specific 2θ angles give information about amount. Analyses results with different characterization techniques such as microscopic analysis, ...

Abstract Effects of reduced (– 40 °C), ambient (20 and elevated (200 °C) deformation temperatures on the microstructure evolution strain hardening behavior two low-C thermomechanically processed high-manganese steels were studied. The was characterized by means scanning electron microscopy (SEM), backscatter diffraction (EBSD), transmission (TEM) techniques. temperature-dependent tendency auste...

Abstract A correlative approach is employed to simultaneously assess structure and chemistry of (carbide boride) precipitates in a set novel Co/Ni-base superalloys. Structure derived from electron backscatter diffraction (EBSD) with pattern template matching, obtained energy dispersive X-ray spectroscopy (EDS). It found that the principal carbide these alloys Mo W rich M 6 C structure. An 2 B b...

Ti40Cu36Zr10Pd14 metallic glass is often considered a promising candidate for biomedical applications, in particular the manufacturing of small size dental implants. Nevertheless, its processing and limited glass-forming ability leads to appearance crystalline spheres called “spherulites”. These spherulites play major role deformation behaviour this alloy. It therefore critical issue future ind...
