ABSTRACT:
A method for producing iron-silicon alloy articles having an improved combination of hot workability and electrical properties; the method comprises taking a molten alloy mass of an iron-silicon alloy from which the article is to be made and gas atomizing it to form alloy particles which are quickly cooled to solidification temperature. These alloy particles are then hot isostatically pressed to form a substantially fully dense article. The fully dense article is then hot rolled to sheet form suitable for example for use as laminates in the manufacture of transformer cores.
