Badania wpływu grubości próbki i rozmiaru ziarna na efekt Barkhausena w blachach zorientowanych
Języki publikacji
Abstrakty
The influence of sample thickness and grain size of Conventional Grain-Oriented (CGO) and High Permeability Grain-oriented (HGO) steels on Magnetic Barkhausen Noise (MBN) of Epstein strips has been examined. It might be expected that MBN decreases with increasing sample thickness due to eddy current damping but the measurements show that the average domain width, hence the grain size influences MBN in strips less than 0.35 mm thick. From 0.35 mm and above, both strip thickness and domain width influence MBN in CGO and HGO.
Zbadano wpływ grubości próbki i rozmiaru ziarna dla stali konwencjonalnej o ziarnie zorientowanym (CGO) i stali o wysokiej przenikalności i ziarnie zorientowaym (HGO) na paskach Epsteina. Można oczekiwać, że amplituda sygnału Barkhausena MBN zmniejsza się wraz ze wzrostem grubości próbki z uwagi na efekt tłumienia od prądów wirowych, lecz pomiary wykazały, że średnia szerokość domen, związana z rozmiarem ziarna, ma wpływ na MBN w paskach o grubości mniejszej niż 0,35 mm. Dla grubości 0,35 mm i powyżej, grubość paska i szerokość ziarna mają wpływ na MBN zarówno dla stali CGO i HGO.
