Evaluation of sintered magnetic cores using EBSD
By using EBSD, it becomes possible to analyze the causes of the deterioration of magnetic properties in soft magnetic metal powder compacts.
The magnetic cores made from soft magnetic powder through compression molding undergo an annealing treatment after compaction. Factors that change with annealing temperature were analyzed using EBSD, and the relationship with coercivity was investigated. As a result, a decrease in KAM value and an increase in average grain size were observed with rising annealing temperature, which showed a tendency for coercivity to decrease. By applying these results, it becomes possible to analyze the causes of magnetic property degradation in compressed magnetic cores made from soft magnetic metal powders using EBSD.
