Description of various degrees of cold plastic deformation structural steel based on Barkhausen noiseGrum, Janez, 1946- ...ǂThe ǂmagnetic Barkhausen effect is a phenomenon occurring during magnetisation of ferromagnetic materials and related to movements of magnetic domains under the influence of an alternating magnetic ... field. Behaviour of magnetic domains is dependent on microstructure characteristics such as grain size and grain orientation, cold deformation, microhardness, residual stresses, dislocations, impurities. The Barkhausen noise is a collection of all information on a material; therefore, voltage signals should be captured, processed and compared to equal signals from the materials having specified properties. The paper shows influences of various degrees of cold deformation. The study is based on an analysis of the voltage signal of the magnetic Barkhausen noise by means of its maximum amplitude, an analysis of its power spectra, and a comparison of the voltage-signal power. In the investigation, a deep-drawing steel DIN St10 in the soft condition, in the form of plate and strips having various initial thicknesses, which were subsequently rolled to a uniform thickness, was used.Vir: Produljenje vijeka trajanja : zbornik radova = Life extension : proceedings (Str. 341-349)Vrsta gradiva - prispevek na konferenciLeto - 1998Jezik - angleškiCOBISS.SI-ID - 2728475
