MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202617076236 A) filed by Obshchestvo S Ogranichennoy Otvetstvennostyu on June 19, 2026, for Device For Determining The Uniformity Of Mechanical Properties Of Articles Made Of Ferromagnetic Materials And Detecting Regions Of Abnormal Hardness Therein.
Inventors include Kirikov, Andrey Vasilievich; and Shelukhin, Alexey Andreevich.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: The invention relates to the field of testing the physical properties of articles and materials and can be used for detecting regions of abnormal hardness and other physical and mechanical surface properties of articles manufactured from ferromagnetic materials, in particular steel sheets, rails, pipes and bars. The technical result of the invention is that of ensuring the necessary measuring accuracy and improving testing efficiency, thereby rendering the claimed device for determining the uniformity of mechanical properties of articles made of ferromagnetic materials suitable for use in testing metal products for the presence of abnormal hardness while on a production line. Proposed is a design for a device for determining the uniformity of mechanical properties of articles made of ferromagnetic materials and detecting regions of abnormal hardness therein. Use of the claimed design makes it possible to prevent the negative effect of regions with residual magnetism in test objects by means of the simultaneous analysis of several frequency components of a signal.
