Abstract
The invention relates to devices for determining the elastic properties of materials by pressing a micro-indenter into the surface of a sample to a given depth in the elastic region. The technical result is that of increasing the technological capabilities of an x-ray microtomograph by allowing imaging of the deformation state of a material without interruption to the application of force, and improving the resolution. The essence of the invention is that a device for 3D imaging of the deformed state of the surface of a material in the elastic region is additionally provided with a special assembly comprising the following axially aligned components: a length of cylindrical tube made of a material that is transparent to x-rays, a micro-indenter, and a device for the linear movement of said micro-indenter. Further, a mechanical force loading unit in the form of a graduated micrometer is coupled to the device for the linear movement of the micro-indenter, and said components are secured to the upper end face of the cylindrical tube, outside of said tube, and the lower end of the tube is connected by a screw connection to a seat for fastening the special assembly to a goniometric stage. In addition, in order to increase the resolution, the distance between a source and a detector of x-ray radiation is selected as equal to 30 ± 5 mm, and the goniometric stage, together with the special assembly, is disposed in the middle between the source and the detector of x-ray radiation.
