Synthesis of a (110) [001] Type Torque Curve in Silicon Iron

Abstract
The orientations and sizes of all the grains in a polycrystalline disk specimen of high-purity 3.25% silicon iron are measured to determine a calculated magnetic torque curve and the texture of the specimen. The torque results agree with the experimentally determined values. The curves approximate a (110) [001] single crystal torque curve, which is reduced about 75%, and thus indicate a possible texture consisting of about 25% (110) [001] and 75% random. The true texture obtained from the orientation data is found to have more than ten components, none of which is (110) [001]. Illustrations showing how a (110) [001] type torque curve may be synthesized from non-(110) [001] type components in the texture are given.
