ADAPTABILITY OF IRON-SILICON MAGNETIC ALLOYS FOR SPECIAL ENVIRONMENTS

Active / Technical Report | Accession Number: AD0251912 | Need Help?

Abstract:

The report presents those intrinsic physical and magnetic properties of the Fe-Si alloy system containing 0 to 6.5 Si by weight that make it particularly suitable for satisfying a majority of these new environmental demands. Numerous comparisons are made between these alloys and the many other existing soft magnetic alloys for purpose of illustrating the preference of one system over another for each particular environmental condition under consideration. Specific emphasis is placed on performance characteristics of Fe-Si alloys at operating temperatures up to 500 C, in nuclear radiation environments of about 10 to the 17th power fast neutronssq cm, and also in environments where effects of oxidation, compression, and special crystalline orientations can influence the stability and efficiency of these materials. A discussion on the effects of magnetic annealing is included. Author
