Method of manufacturing amorphous magnetic alloy ribbon and use for magnetostriction delay lines

摘要

The amorphous magnetic alloy ribbon for magnetostriction delay lines are prepared by annealing the ribbon having a negative magnetostriction constant at a temperature lower than the crystallization temperature of the alloy under a tension sufficiently enough to support the ribbon substantially straight between the both ends thereof.P P The ribbon thus prepared permits a decrease in a deviation in a distribution of internal stresses and the propagation speeds of magnetostriction vibration through the ribbon.
