A Unique Quenching and Deformation Dilatometer for Combined In Situ Neutron Diffraction Analysis of Engineering Materials

Abstract

A modified quenching and deformation dilatometer is now in operation at the Heinz Maier‐Leibnitz Zentrum neutron center. It is customized for running neutron scattering measurements during the temperature/deformation treatment of the sample, in particular neutron diffraction (phase, texture, lattice strain) and neutron small angle scattering. Further details can be found in the article number http://doi.wiley.com/10.1002/adem.202100163 by Xiaohu Li, Weimin Gan, and co‐workers.

Light alloying element-regulated noble metal catalysts for energy-related applications

“…Over the past few decades, advances in spallation neutrons, synchrotron X-rays, and super-computing power have driven the development of more powerful diffraction techniques, such as synchrotron X-ray diffraction (SXRD), neutron diffraction, and X-ray pair distribution function (XPDF). The SXRD and neutron diffraction techniques can offer higher sensitivity to light alloying atoms in materials consisting of heavy atoms, and gain highly accurate structural information about phase fraction, lattice strain, structure distortion, and preferred orientation [101,109,110]. For example, Chen et al [78] characterized a PdBx catalyst using SXRD, and identified interstitial boron-induced local distortion and the appearance of a minor hcp phase in the fcc Pd lattice.…”
