Back in 1957 I worked for a company that was planning to get into high
voltage distribution transformers for electric utilities. The idea was to
use a wound core of something other than the conventional silicon steels and
obtain the desired properties through an annealing process. Prototypes were
made but the project never got off the ground. I suggest you do a patent
search on the U.S Patent Office web site. This could possibly give you some
insight as to what has been attempted.

Hi Eric,

Heat treating with the objective to enhance magnetic properties is an
interesting subject. One of the best references on this subject I
have come across is:

Ferromagnetism by Richard M. Bozorth, IEEE Press ISBN o-7803-1032-2

It is not cheap but well worth it! You can order it online if I am
not mistaken - through IEEE.org

Other than heat treating, it also deals will Alloying, Stress and
Magnetistriction, Temperature and Curie Point to name a few. A very
comprehensive text.

Regards,

Martin
