Quenched-in Stresses In Amorphous Ribbons

A set of four samples of the composition Fe73.5Cu1Nb3Si13.5B9 produced with different quenching rates was investigated in the amorphous state. In addition to disaccommodation experiments, the stress dependences of the coercivity and of the pinning field were also determined. The stress dependence of the coercivity was fitted using a pinning model. These data show the effects of anisotropy fluctuations as well as of the surface roughness. © 1994.1331-32023Yoshizawa, Oguma, Yamauchi, (1988) J. Appl.
