THE SINGULARITY OF CONCENTRATION DEPENDEN CES OF MECHANICAL AND MAGNETORESONANT PROPERTIES OF FE-B METALLIC GLASSES AT LOW-TEMPERATURES

The concentration dependences of the yield stress have been measured i n metallic glasses Fe100-xBx (x = 14, 15, 16, 17, 18, 20) under the un iaxial tension as well as those of the local magnetization and g-facto r by the ferromagnetic resonance method. The singularity of these prop erties is found to be characteristic of the eutectic composition (x = 17). The established regularity may be attributed to a severe disorder ing of the Fe83B17 glass at intercluster boundaries due to a specific structure of clusters in this metallic glass.
