MAGNETIC MATERIALS IN RELATION TO STRUCTURE 41 



An important consideration in connection with the new materials is 

 the broadening of the field of possible new magnet alloys. Previously 

 it had been generally considered that the field of useful permanent 

 magnet materials was confined to the plain and alloy steels. The new 

 metallic materials are systems which are precipitation hardening, and 

 suggest possibilities for developing useful alloys in other similar systems 

 of iron.
