DETERMINATION OF THE EFFECT OF MECHANICAL DEFORMATION ON THE MAGNETIC PROPERTIES OF MATERIALS

Cilj diplomske naloge je bil ugotoviti vpliv mehanskih obremenitev in deformacij na magnetne lastnosti vzorcev iz magnetne pločevine oziroma iz elektropločevine. Vse meritve smo izvedli na hladno valjani, neorientirani pločevini M600–50A. Vplive smo ugotavljali z enoploščnim merilnikom magnetne pločevine, katerega smo prilagodili tako, da je bilo možno med meritvijo vzorec tudi mehansko obremeniti. Poudarek diplomske naloge je bil na primerjavi merjenih rezultatov med mehansko obremenjenim in neobremenjenim vzorcem.The main purpose of my diploma thesis was to establish the influence of mechanical strain and deformation on magnetic properties of specimens made from magnetic sheet or electrical steel sheet. All measurements were executed on cold rolled non-oriented sheet M600–50A. We found out the effects with magnetic sheet by means of single sheet tester, which was adjusted in a way, that there was a possibility of mechanical strain during the measurement of specimen. The emphasis of my diploma paper was the comparison of two measured results between mechanically strained and restrained specimens
