The tensile-shear strength of laser-welded lap joints developed in abrasion resistance ultra-high ARS-600 steel was optimized by evaluating the achieved with different welding parameters and various configurations weld patterns, including multiple continuous longitudinal transverse weldments. microstructural evolution fusion zone characterized electron backscatter diffraction (EBSD) after value...

It is well known that oriented iron and titanium oxide inclusions occur in pyroxenes and plagioclase of anorthosites and granulites, and they are attributed to exsolution at subsolidus conditions. The oxides occur as needles or platelets. In this study, we determine the morphology of oxide needles as well as their orientation in plagioclase (An 30–35) in anorthosite gneiss from the Adirondack m...

The spatial resolution of the electron backscatter diffraction signal is explored by Monte Carlo simulation for the sigma phase in steel at a typical instrumental set-up. In order to estimate the active volume corresponding to the diffracted electrons, the fraction of the backscattered electrons contributing to the diffraction signal was inferred by extrapolating the Kikuchi pattern contrast me...

Abstract The evolution of micro-strain and crystallographic texture each phase α+β Ti-6Al-4V titanium alloy generated during tensile deformation has been estimated numerically then compared with the experimental results. It carried out based on Crystal Plasticity Finite Element Model (CPFEM) simulation stress-strain curve till uniform elongation for equiaxed microstructure is synthetically. syn...

Introduction: Most martian meteorites are highly shocked, with plagioclase transformed to maskelynite or even melted and partially crystallized [1,2]. These responses to shock conditions on Mars provide clues to the nature of the ejection events for martian meteorites and to local shock conditions. Where new-to-science phases are discovered, meteoritic occurrences can also inform the study of e...

Grain boundaries play a vital role in materials science, and they are extensively studied through experimental numerical methods. Electron backscatter diffraction (EBSD) is commonly used to characterize crystalline materials, yet its performance often compromised at grain boundaries. The key difficulty index the overlapped electron patterns, where Kikuchi bands from multiple crystal orientation...

As a step towards resolving the genesis of inclusions in diamonds, a new technique is presented. This technique combines cathodoluminescence (CL) and electron backscatter diffraction (EBSD) using a focused ion beam– scanning electron microscope (FIB–SEM) instrument with the aim of determining, in detail, the three-dimensional diamond zonation adjacent to a diamond inclusion. EBSD reveals that m...
