摘要： An alloy comprised of 45 to 53 wt. % Ni with the remainder iron, and including small amounts of deoxidizing and processing additives is worked into a 0.01 to 0.1 mm thick tape, wound to form a tape core and is then subjected to a final annealing for at least one hour at a temperature of at least 900.degree. C. and thereafter is subjected to a tempering in a magnetic cross-field (i.e., the magnetic lines of force are applied in the plane of the tape perpendicular to the rolling direction thereof). The process provides high impulse permeabilities at induction rises of 1T or larger within the so-processed tape cores. Particularly high impulse permeabilities are achieved in instances where an anisotropic structure with a privileged grain direction in the rolling direction is generated in the tape material via heating and final deformation before winding into a tape core and via a final annealing after winding of the tape core. The so-produced tape cores are useful in various electrical applications, particularly in pulse transformers and thyristor choke coils.

摘要： The invention herein disclosed is directed to novel magnetic cores, particularly magnetic tape-wound cores, and to a new, novel and less expensive method of manufacture. The alloys employed in the manufacture of these cores employ smaller quantities of expensive metals such as nickel and, accordingly, result in substantial savings. The cores are exceptionally useful because of their high available flux-density change and high pulse permeability. Generally, the alloys employed contain nickel contents of from about 49 to 56 percent by weight of the alloy, and the remainder is substantially iron and small quantities of additives. The magnetic core is heat treated in a hydrogen atmosphere for several hours, cooled to room temperature, then reheated above the Curie Point and then cooled in a transverse magnetic field. Alternatively, it is possible to cool to just above the Curie Point, and omit the room temperature cooling and subsequent reheating.
