Questions and Answers About the µ-X360J X-ray Diffractometer
The µ-X360J is the latest generation of a portable X-ray diffractometer for the rapid and reliable determination of residual stresses and residual austenite in metal components. By changing the tube, it can be used for many different metals, alloys and ceramics. It replaces the established µ-X360s and sets new standards in precision, speed and ease of use.
The µ-X360J offers greater precision, faster measurement times and significantly improved usability. It also enables more stable and efficient measurement processes, as well as enhanced automation through the optional StressEasy software.
The system is suitable for determining residual stress and residual austenite in metallic components. Typical applications include assessing material condition, determining fatigue strength and ensuring quality control at individual stages of production. It also provides information on dislocation density, texture and coarse grain.
Yes, thanks to its ease of positioning and short measurement times, the µ-X360J is ideal for use both in the laboratory and directly on the production floor.
You need to set the parameters for the measurement angle, measurement position and measurement distance. Useful aids are available for each of these: the device has a built-in protractor, the position is marked by a red LED, and the distance does not need to be set to the nearest millimetre, as the software can calculate the exact distance from the measurement signal.
The µ-X360J has been specifically designed for ease of use. Features such as automatic calibration and easy replacement of components significantly reduce the effort required to operate the device.
The tube module can be replaced quickly and easily using a plug-in system once the two fixing screws have been loosened. The integrated collimator also allows for flexible adjustment of the spot size.
The larger detector allows for a greater measurement distance, which improves accessibility and increases the resolution of the measurement signal.
The optional StressEasy software enables extensive automation of measurement processes. This includes stress mapping, batch measurements and integrated setpoint checks for production lines.
Yes, when combined with a six-axis robot, this creates a highly automated system. Measurements can be fully digitised and carried out sequentially without any user intervention.
Stress mappings enable a comprehensive analysis of residual stress states. On the µ-X360J, these can be customised and supplemented with oscillatory movements at selected positions.
The detector stores information most effectively within a specific intensity range. If the intensity is too low or too high, the measurement time is adjusted accordingly.
Close the programme, then unplug the USB cable and plug it back in again.
First, recalibrate the device. Also check whether the sample has a coarse grain or texture — if so, switch to oscillation mode. Verify that the correct material has been selected and the appropriate angle is set. Note that even a coating of just a few micrometres can cause the device to shut down.
The sample is likely to be coarse-grained or have a coarse texture. Switch the device to oscillation mode to compensate for this effect.
The area that is obscured has a significant impact on the measurement error, which is why only the relevant portion of the ring is used.
The X-rays used are very low-energy at 12 keV. For comparison, the radiation used for chest X-rays is more than 10 times as energetic.
