Surface damage induced by mechanical polishing of cold-rolled and annealed Pd specimens was examined cross-sectional electron backscatter diffraction (EBSD) measurements. Fine grains with high-angle grain boundaries were detected in the outermost layer both specimens. Less granular but layered gradation crystallographic orientation sub-surface specimen. In specimen, a lot elongated entire inner...

A dedicated in situ heating setup a scanning electron microscope (SEM) followed by an ex atomic force microscopy (AFM) and backscatter diffraction (EBSD) is used to characterize the nucleation early growth stages of Fe-Al intermetallics (IMs) at 596 {\deg}C. location tracking interpret further characterization. Ex AFM observations reveal slight shrinkage out plane protrusion IM onset directiona...

In this work, quasi in-situ electron backscatter diffraction (EBSD) was applied to study an early stage of the abnormal grain growth occurring in friction-stir welded 6061 aluminium alloy during post-weld solution heat treatment. It found that catastrophic completed heating annealing treatment, and further static storage at solutionsizing temperature provided almost no microstructural changes.

Abstract Currently, the automated electron backscatter diffraction (EBSD) technique only allows differentiation of Laue groups based on an pattern (EBSP). This article shows that information concerning lattice plane polarity is not stored in EBSP, but also Hough transformed EBSP where it can be easily accessed for evaluation. Polar Kikuchi bands lead to asymmetric peaks during transformation ar...

Plastic deformation of α′ martensite phase in Ti-6Al-4V alloy is investigated by performing tensile tests a Scanning Electron Microscope (SEM). Backscatter Diffraction (EBSD) analysis used to determine the slip modes activated depending on crystallographic orientation laths. As α phase, mostly basal and prismatic are identified. The weighted Schmid applied using critical resolved shear stress (...

An unusual microcrystalline quartz texture has been recognized in the investigation of pervasively silicified ore-bearing horizons occurring in the uppermost part of carbonate platform sequences of different ages (from Precambrian to Mesozoic) and of different geotectonic settings. This peculiar texture has been labeled “grid-work texture”, and derives only by a rather fast and preferred crysta...

Although carbonate-precipitating cyanobacteria are ubiquitous in aquatic ecosystems today, the criteria used to identify them in the geological record are subjective and rarely testable. Differences in the mode of biomineralization between cyanobacteria and eukaryotes, i.e., biologically induced calcification (BIM) vs. biologically controlled calcification (BCM), result in different crystallogr...

Austenitic stainless steels offer good property combinations for structural component applications in demanding and aggressive environments, including nuclear power plants, where irradiation assisted degradation failures have been reported [1]. Enhanced irradiation tolerance has been reported for materials containing a high density of internal interfaces that act as point defect annihilation or...
