BULK MATERIAL IDENTIFICATION METHOD AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2013 - IPC G01N19/00 B82Y35/00 

FIELD: nanotechnologies.

SUBSTANCE: probe tip is located near the investigated material, an increasing load is applied to the probe and value of applied load and depth of probe penetration is measured by means of a converter at that point. Tested bulk material is placed in a cell in the form of a cylindrical seat and the material is provided with action of a probe in the form of a stock with a flat end face. Load value is programmed and transferred through a controller to a measuring and power head including a microloading device, and submersion depth is measured with a precision optic sensor of local deformations and initial test data is transferred to the computer. The instrument includes a housing, a loading device connected to the device supplying it to the tested material, a loading value sensor for continuous measurement of loading force variation, which is applied to the probe holder, a displacement sensor for continuous measurement of varying depth of the probe submersion into the material, and the computer. Loading device is made in the form of a power cell and a precision optic sensor for measurement of local deformations of the specimen. In addition, the instrument includes a controller for control, accumulation and processing of data flows, which is provided with programmable force value control. Probe is made in the form of a cylindrical stock with a flat end face and installed above the cell with the specimen. Cell includes contacts for measurement of electric resistance.

EFFECT: increasing the resolution in relation to physical and mechanical properties of bulk nanopowder materials and increasing controlled parameters and properties.
