Mapping orthorhombic domains with geometrical phase analysis in rare-earth nickelate heterostructures

Duncan Thomas Lindsay Alexander, Bernat Mundet, Jean-Marc Triscone

Most perovskite oxides belong to the Pbnm space group, composed of an anisotropic unit cell, A-site antipolar displacements, and oxygen octahedral tilts. Mapping the orientation of the orthorhombic unit cell in epitaxial heterostructures that consist of at ...

EBSD study of variant reorientation, texture, and twin formation in a martensitic NiTi alloy deformed in compression

Roland Logé, Cyril Cayron, Mathijs Pieter van der Meer, Junfeng Xiao

Martensitic crystallography plays a vital role in the texture evolution and mechanical properties in Nickel-Titanium (NiTi) shape memory alloys when subjected to deformation. However, their microstructural changes during deformation are not well known and ...

Experimental Analysis of Ductile Cutting Regime in Face Milling of Sintered Silicon Carbide

Lorenz Hagelüken

In this study, sintered silicon carbide is machined on a high-precision milling machine with a high-speed spindle, closed-loop linear drives and friction-free micro gap hydrostatics. A series of experiments was undertaken varying the relevant process param ...

System and method for removing scalloping and tapering effects in high aspect ratio through-silicon vias of wafers

Edoardo Charbon, Sandro Carrara, Simone Frasca

A method for manufacturing vias in a silicon wafer, the silicon wafer having a crystal orientation, and having a plane that is perpendicular to a surface of the wafer, tilted by 35.26°, the method comprising the steps of providing a mask having ...

Deformation twinning on a plane is a simple shear that transforms a unit cell attached to the plane into another unit cell equivalent by mirror symmetry or 180 degrees rotation. Thus, crystallographic models of twinning require the determination of the sho ...

Cutting Materials in Half: A Graph Theory Approach for Generating Crystal Surfaces and Its Prediction of 2D Zeolites

Berend Smit, Peter George Boyd, Senja Dominique Barthel, Matthew David Witman

Scientific interest in two-dimensional (2D) materials, ranging from graphene and other single layer materials to atomically thin crystals, is quickly increasing for a large variety of technological applications. While in silico design approaches have made ...

Cast aluminium single crystals cross the threshold from bulk to size-dependent stochastic plasticity

Andreas Mortensen, William Curtin, Csilla Mikó, Jérôme Krebs, Suzanne Godelieve Alphonsine Verheyden, Satish I Rao

Metals are known to exhibit mechanical behaviour at the nanoscale different to bulk samples. This transition typically initiates at the micrometre scale, yet existing techniques to produce micrometre-sized samples often introduce artefacts that can influen ...

The formation of a vein during cyclic shearing of a single copper crystal oriented for single slip can be followed in transmission Laue diffraction by analyzing the spatially resolved lattice rotation evolution. Because Laue transmission integrates the sig ...

Angular distortive matrices of phase transitions in the fcc-bcc-hcp system

Cyril Cayron

This work generalizes the one-step model previously developed on fcc-bcc martensitic transformations to the larger family of phase transitions in the fcc-bcc-hcp system. The angular distortive matrices are calculated for the bcc-fcc, bcc-hcp and fcc-hcp tr ...

In-situ Laue diffraction to follow dislocation patterning during fatigue

Ainara Irastorza Landa

The macroscopic strength of metals is determined by the dislocation arrangements that are formed when dislocations slip in the crystal lattice in response to the applied stress. Despite the extensive research carried out, the transition from uniform to non ...
