Study on Measurement Technique for Lattice Spacing at Strain Free by Neutron Diffraction Method
For precise stress analysis of engineering materials by diffraction methods, the lattice spacing of strain-free materials, d0, must be accurately measured and determined. In this study, a new and easy technique of measuring the specimen is proposed which involves using the original material instead of its powder form for accurate estimation of d0 . The value of d0 obtained by our technique is e...
متن کاملTheory of Neutron Diffraction from the Vortex Lattice in UPt3
Neutron scattering experiments have recently been performed in the superconducting state of UPt3 to determine the structure of the vortex lattice. The data show anomalous field dependence of the aspect ratio of the unit cell in the B phase. There is apparently also a change in the effective coherence length on the transition from the B to the C phases. Such observations are not consistent with ...
متن کاملSimultaneous resonant x-ray diffraction measurement of polarization inversion and lattice strain in polycrystalline ferroelectrics
Structure-property relationships in ferroelectrics extend over several length scales from the individual unit cell to the macroscopic device, and with dynamics spanning a broad temporal domain. Characterizing the multi-scale structural origin of electric field-induced polarization reversal and strain in ferroelectrics is an ongoing challenge that so far has obscured its fundamental behaviour. B...
متن کاملDepth capabilities of neutron and synchrotron diffraction strain measurement instruments. II. Practical implications
In part I [Withers (2004). J. Appl. Cryst. 37, 596±606], a framework was presented for estimating the maximum feasible penetration length for neutron and synchrotron X-ray strain measurement. This calculation re ̄ected the attenuation and scattering capability of the material under examination, the incident ̄ux and detector arrangement, the likely background signal, the required strain measuremen...
متن کاملNeutron Larmor Diffraction for the Determination of Absolute Lattice Spacing
The Neutron Larmor diffraction method is applied for the first time to determine absolute lattice spacing of a Silicon powder and polycrystalline IN718 samples. The absolute value of lattice spacing can be measured to an accuracy of 7· 10A. However, absolute determination of the lattice parameter is limited by the quality of the reference specimen used. Absolute lattice spacing determined by La...
