TLDR
In this article, a 3% macroscopic strain was obtained in the composite on loading and was fully recovered on unloading, and the diffraction spectra were analyzed by Rietveld refinement that included a spherical harmonic description of the texture and a lattice plane dependent formulation of the elastic strain.About:

Residual stress. Part 2 – Nature and origins
TL;DR: In this paper, the authors examine the nature and origins of residual stresses across a range of scales, from the long range residual stress fields in engineering components and welded structures, through the interphase stresses present in composites and coatings, to the microscale interactions of phase transformations with local stresses.
Journal ArticleDOI
Residual stress and its role in failure
TL;DR: In this article, the origins of residual stress are understood, opportunities for removing harmful or introducing beneficial residual stresses recognized, their evolution in-service predicted, their influence on failure processes understood and safe structural integrity assessments made, so as to either remove the part prior to failure, or to take corrective action to extend life.

Study of slip mechanisms in a magnesium alloy by neutron diffraction and modeling
TL;DR: In this paper, the internal strains within a polycrystalline magnesium alloy plate have been measured during tensile and compression testing in situ by neutron diffraction using an elasto-plastic self-consistent simulation code.
Journal ArticleDOI
High strength, low stiffness, porous NiTi with superelastic properties
TL;DR: The unique combination of low stiffness, high strength, high recoverable strains and large energy absorption of porous superelastic Ni Ti, together with the known biocompatibility of NiTi, makes this material attractive for bone-implant applications.
Journal ArticleDOI
R-phase transformation phenomena in thermomechanically loaded NiTi polycrystals
TL;DR: In situ neutron diffraction and ultrasonic experimental techniques have been used to investigate the B2M R transformation and R-phase reorientation processes occurring during thermal, mechanical and thermomechanical loading of NiTi shape memory alloy polycrystals as discussed by the authors.

A profile refinement method for nuclear and magnetic structures
TL;DR: In this paper, a structure refinement method was described which does not use integrated neutron powder intensities, single or overlapping, but employs directly the profile intensities obtained from step-scanning measurements of the powder diagram.

Physical properties of crystals
TL;DR: In this paper, the physical properties of crystals systematically in tensor notation are presented, presenting tensor properties in terms of their common mathematical basis and the thermodynamic relations between them.
