Effect of the Interaction of Lattice Defects with Solute Atoms upon the Magnetic Properties of Soft Magnetic Materials: I. Effect of Strain Aging on the Q UASISTATIC Magnetic Hysteresis Loop

摘要

In the Fe-3 wt percent Si alloys used as electrical-sheet steels, a quasistatic hysteresis loop of a special type was found; the loop had an inflection separating it into two regions with different slopes. Such a loop is peculiar to only a coarse-grained material with a (110)(001)texture rolled in the (001) direction and annealed at certain temperatures. The observed features of the loop are caused by strain aging, upon which changes in the magnetic phases occur that increase the difference between their magnetic hardnesses.
