Investigation of α-Ti plastic anisotropy under thermomechanical loadings: temperature influence on deformation mechanisms [PDF]

MATEC Web of Conferences, 2020
In situ neutron diffraction method has been used to investigate deformation mechanisms (slip and twinning deformation modes) during uniaxial tensile tests of extruded a-titanium alloy at room temperature, 100 and 300 °C.

Measurement of strain evolution in overloaded roller bearings using time-of-flight neutron diffraction

Materials & Design, 2020
Neutron diffraction is an established method for non-destructively characterising residual stress or observing in situ strain during external stimuli. Neutron based stroboscopic techniques have previously been introduced for measuring strains undergoing ...

A flow-through hydrothermal cell for in situ neutron diffraction studies of phase transformations [PDF]

, 2006
A flow-through hydrothermal cell for the in situ neutron diffraction study of crystallisation and phase transitions has been developed. It can be used for kinetic studies on materials that exhibit structural transformations under hydrothermal conditions.

In-situ neutron diffraction during biaxial deformation

Acta Materialia, 2016
A change in strain path may have a significant effect on the mechanical response of metals. In order to understand or even predict the macroscopic behaviour under such conditions a detailed knowledge on the microstructural evolution is crucial. Yet relatively little work has been done to quantify and understand how the inter- and intragranular strains ...

Recent Progress of Residual Stress Distribution and Structural Evolution in Materials and Components by Neutron Diffraction Measurement at RSND

Quantum Beam Science, 2018
Neutron diffraction is an effective and nondestructive method to investigate inner structure and stress distribution inside bulk materials and components. Compared with X-ray diffraction, neutron diffraction allows a relatively high penetration depth and

In-Situ Anaerobic Heating of Human Bones Probed by Neutron Diffraction

Analytical Chemistry, 2023
The first neutron diffraction study of in-situ anaerobic burning of human bones is reported, aiming at an interpretation of heat-induced changes in bone, which were previously detected by vibrational spectroscopy, including inelastic neutron scattering techniques.
