The amount of twin formation of electroplated and thermally treated copper thin films was evaluated by electron back-scattering diffraction (EBSD) analysis. The result establishes the importance of twin formation in the analysis of stress-induced voiding, and indicates that with the inclusion of a copper alloy co-element, twin formation was significantly reduced relative to pure-copper. Further...

We analyze the contrast reversal of Kikuchi bands that can be seen in electron backscatter diffraction (EBSD) patterns under specific experimental conditions. The observed effect can be reproduced using dynamical electron diffraction calculations. Two crucial contributions are identified to be at work: First, the incident beam creates a depth distribution of incoherently backscattered electrons...

The complex mineralogy and low concentration of silver in polymetallic ores makes mineralogical characterization extraction challenging. In this study, quantified the flotation products from batch tests was undertaken for a silver-rich zinc-lead ore using QEMSCAN® (Quantitative Evaluation Minerals by Scanning Electron Microscope), scanning electron microscope with an energy dispersive spectrome...

The data presented in this article are related to the research article entitled "Cyclic Shear behavior of conventional and harmonic structure-designed Ti-25Nb-25Zr β-titanium alloy: Back-stress hardening and twinning inhibition" (Dirras et al., 2017) [1]. The datasheet describes the methods used to fabricate two β-titanium alloys having conventional microstructure and so-called harmonic structu...

A significant proportion of Europe’s lithium endowment is hosted by unconventional resources such as rare-metal granites (RMG) which the Beauvoir granite in France a prime example. In hard-rock deposits, where mostly micas (lepidolite, zinnwaldite), ability to assess whether can be extracted economically from ore essential and requires comprehensive understanding mineralogical properties deport...

This article, dedicated to the memory of the late professor Raimond Castaing, will evoke the birth and the first developments of electron probe microanalysis in France.
