چکیده
The wide range of possible applications for the portable X-ray apparatus with an air cooled double-anode X-ray tube are presented. The apparatus is provided with a stress measurement unit and focusing camera for phase analysis. The distinctive characteristics of the apparatus are a small weight (a 4 kg), fine focus ray tube, portability and ease of use for both laboratory samples and industrial components. In the present paper the technical characteristics of the equipment, the methodology and experimental results are described. The most important of these are the following: measurements of tensile force in pre-stressed steel cables in concrete, residual stress measurements in railway wheels, stress measurements at elevated (up to 3OO’C) temperatures and stress measurements in welded joints including stresses in the weld bead and heat affected zone.

Study on Evaluation of Residual Phase Stress of the Dual Phase Stainless Steel
In this study , we measured residual stress in ground layer of ( CY+ r )dual phase stainless steel by X-ray diffraction. In addition, the influence of changing depth of cut on residual stress was investigated. It was found that residual stress in the a! phase was dependent on depth of cut, while the stress in Y phase was not affected by depth of cut. As a results of stress measurement under app...
متن کاملX-Ray in-situ saturation monitoring, an aid to study relative permeability in water-wet carbonate rocks
The simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. Relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. Nowadays X-ray scanners are one of the most...

In this study the characteristics of two different kinds of La0.6Sr0.4Co0.2Fe0.8O3 (LSCF) powders, one in-house synthesized powder by a co-precipitation method and another one purchased from Fuel Cell Materials Co. (FCM Co., USA), were compared. The co-precipitated powder was prepared by using ammonium carbonate as precipitant with a NH4+/NO3- molar ratio of 2 and calcination at 1000C for 1 h....

[1] Polycrystal elasticity of the unquenchable MgSiO3 high-pressure clinoenstatite has been measured using ultrasonic interferometry in conjunction with in-situ X-ray diffraction and imaging techniques within its stability field in a large volume multi-anvil apparatus for the first time. At 6.5 GPa, we obtained @KS/@P = 5.6(3), @G/@P = 1.5(1), @KS/@T = 0.017(1) GPa K 1 and (@G/@T) = 0.015(1) GP...
متن کاملComparative Harmonic Loss Measurement of Grain Oriented and Non-oriented Magnetic Sheets Using a High Precision Single Sheet Tester
Abstract: Local flux may be distorted in many regions of core, although total flux is usually sinusoidal. When attempting to predict the loss distribution in materials operating under localized distorted flux conditions, which occur in machines and transformer cores, it is essential that proper account of the waveform be taken. Moreover for development of new magnetic materials and generation ...
