Abstract
To test a mock-up of a hand-held X-ray diffractometer intended for determining the surface stresses in the important parts of rail transport, we propose to use control samples subjected to elastic deformation by three-point bending. The results obtained with hand-held and stationary X-ray diffractometers and the calculated stresses are compared. The stresses to be compared agree well within the limits of an acceptable error.
