Description

A device is developed to provide fast and reliable measurement of stress and strains in parts of machines, apparatus and installations. Basic components of the device are miniature air-cooled X-ray tubes (5 watt capacity), detector, goniometer and electronic block.

A part to be investigated is radiated with primary X-ray beam, secondary reflected beam is registered with use of detector and electronic block. On the base of registered data stress/ strain characteristics are calculated and compared with critical values (e.g. yield strength). Due to use of special software obtained information can be applied for prediction of operative life of the part has been tested.

Benefits

Low radiation.
Due to low tube capacity (from 2.4 to 5.0 W) the radiation level at the distance of 12 cm (4.0 inches) from a place being exposed to X-ray beam doesn�t exceed natural background level. In accordance with measurements the exposition capacity at the distance of 100 mm from tube window is in a range from 11 to 40 R/min. So there is no need to use special protective shield against X-ray radiation. The use of diffractometer is harmless for human beings and nature.

Portability
The diffractometer has dimensions which are comparable with ones of modern PC dimensions. Total weight of the device is about 20 kg (44 pounds). Low weight of the diffractometer provides the use of it directly in working site (e.g. pipeline diagnostics in field condition). Specially for using in field conditions the diffractometer can be supplied with small 350 W power electric generator driven by internal combustion engine.

High operating rate.
An exposition time varies in range of 0,5 - 15 min depending upon the material of object to be tested and presence or absence of monochromators. It took only 20 - 40 min (depending upon working conditions, object to be tested etc.) to prepare the diffractometer for carrying out measurements. Short exposition time and fast data processing provide carrying out real-time diagnostics.

Simplicity of exploitation.
The diffractometer may be handled only one person. Diffractometer control panel has three buttons and four indicators. Due to application of special software for performing stress and strain express analysis both �omega� and �square psi sine� methods can be used. By customer�s request the device may be supplied with any fastening unit (for example tripod, magnet or vacuum unit).

Data reliability
Numerous stress/strain studies of high-pressure vessels, welded joint, parts of aircraft, turbine blades and so on have proved reliability and precession of data obtained by the use of the diffractometer. ..

Project development

More than 10 diffractometers have been built and operated.

Legal protection of technologies

Russian and Eurasian Patents.

Application, commercial use

Turbine.
The diffractometer was successfully used for measuring stresses in turbine and compressor blades, wheel rims, blade�s locks and so on. Such measurements are necessary to provide safety of turbine exploitation and aircraft safety.

High pressure vessels and pipe lines.
The diffractometer can be used for stress analysis of pipe lines in field conditions and pressurized vessels and tanks.

Railways and bridges.
The diffractometer can be used to check safety of railroad rails and stressed components of railroad and highway bridges.
