Influence of Niobium as Microalloying Element in 3%Si Steel Grade for Electrical Industry
Journal Title: Analele Universitatii "Dunarea de Jos" din Galati. Fascicula IX, Metalurgie si Stiinta Materialelor - Year 2012, Vol 35, Issue 3
Abstract
The paper presents the results of the laboratory research on the chemical composition and crystallographic texture in 3% Si steels and their influence on the level of magnetic losses in the final sheet. The magnetic properties have been estimated by means of the core losses observed on samples taken from the three steels after the secondary annealing. It has been noticed that the microalloyed Nb steel showed the highest percentage of Goss texture in the final sheet and the lowest values of the magnetic losses of the three steels under study.
