Crystal structure of modulated martensite and crystallographic correlations between martensite variants of Ni50Mn38Sn12 alloy

Crystal structure, morphological and crystallographic features of microstructure in 4O modulated martensite of NiMnSn alloy were systematically studied, aiming to provide some fundamental knowledge on the understanding of its multifunctional properties and the further performance optimization.

WavePropaGator: interactive framework for X-ray free-electron laser optics design and simulations

The WavePropaGator (WPG) package is a new interactive cross-platform open-source software framework for modeling of coherent and partially coherent X-ray wavefront propagation. The WPG addresses the needs of beamline scientists and user groups to facilitate the design, optimization and improvement of X-ray optics to meet their experimental requirements. The paper presents a general description of the package and gives some recent application examples.

Simultaneous determination of tensile and shear strains of crystalline bilayers using three Bragg reflections of X-rays

The simultaneous determination of tensile and shear strains in crystals and multilayers using three Bragg reflections of X-rays is described.

The orientation relationship of nanobelt-like Si2Hf precipitates in an Al–Si–Mg–Hf alloy

The orientation relationships (ORs) between the Al matrix and Si2Hf precipitates in an Al–Si–Mg–Hf alloy were investigated. The habit planes of four ORs are rationalized and the formation of Si2Hf precipitates with a nanobelt-like morphology is interpreted by a near-coincident site lattice distribution.

Condor: a simulation tool for flash X-ray imaging

Condor, an open-source simulation tool to predict X-ray scattering amplitudes for flash X-ray imaging experiments, is introduced.

Diamond drumhead crystals for X-ray optics applications

Numerous applications in X-ray crystal optics and instrumentation require ultra-thin perfect diamond single crystals, just a few microns to a few tens of microns thick, properly functioning under Bragg diffraction conditions. Reported here are the successful manufacture and characterization of diamond drumhead crystals, monolithic crystal structures comprised of a thin membrane furnished with a surrounding solid collar, using picosecond laser milling. This opens up new perspectives in the realisation of optical devices that are in high demand to further advance X-ray science and technology.

Rotation of X-ray polarization in the glitches of a silicon crystal monochromator

Rotation of X-ray polarization at the glitches of a monochromator composed of single crystals of silicon is observed. This effect can be explained by a model taking full account of the X-ray source, the effects of multiple-beam dynamical diffraction, and the coherent and Compton scattering from the sample.

Accepted 3 June 2016

Stability of TaC precipitates in a Co–Re-based alloy being developed for ultra high temperature applications

A study of TaC precipitate stability in a Co–Re-based alloy for high-temperature application is presented. Complementary methods such as small-angle neutron scattering, X-ray diffraction, neutron diffraction and scanning electron microscopy characterize the precipitates under various heat treatments.

Accepted 23 May 2016

Bragg–Laue X-ray dynamical diffraction on perfect and deformed lateral crystalline structures

The two-dimensional dynamical theory of X-ray Bragg–Laue diffraction has been developed for deformed lateral crystalline structures having a rectangular cross section. This approach allows one to calculate rocking curves as well as reciprocal-space maps for both the transmitted and reflected wavefields. The approach can be used in coherent diffraction imaging to simulate far-field diffraction patterns produced by relatively large, deformed crystals.
