CURVATURE-REDUCTION ANNEALING OF AMORPHOUS METAL ALLOY RIBBON |
摘要 |
A longitudinal curvature in an amorphous metal alloy ribbon (32) is reduced by heat-treatment. While the heat-treatment occurs, the alloy ribbon (32) is bent "backwards" against the longitudinal curvature, to reduce the amount of heat-treatment required. The process is carried out continuously by transporting the alloy ribbon (32) from reel (36) to reel (38), while wrapping the ribbon (32) around a heated roller (34). Using a discrete strip cut from the alloy ribbon (32) subjected to the curvature-reducing process, a magnetomechanical EAS marker (24') is constructed that has a relatively low profile, while retaining desired magnetic properties.
