Method for improving the magnetic properties of wound core fabricated from amorphous metal

摘要

A method for improving the magnetic properties of a core fabricated from at least one strip of amorphous metal wound about itself to form adjacent laminations in the shape or a closed loop is disclosed. In accordance with the method, a force in tension of predetermined strength is applied to the loop from the innermost lamination of the loop outwardly. While this tensile force is being applied, the loop is annealed simultaneously and subjected to a magnetic field of predetermined strength.
