Abstract: This paper covers the investigation of the microstructure and magnetic properties of amorphous magnetic alloy Fe78Ni1Si9B12 films, which was subjected to thermal processing. Study of the surface with the help of phase analysis and Kikuchi-diffraction revealed the change of state of the alloy surface without the influence on its volume.

Abstract: Vickers and nano indentations were performed on a structurally relaxed Zr41Ti14Cu12.5Ni10Be22.5 bulk metallic glass (BMG), and the evolution of the shear bands in the relaxed BMG was investigated and compared to that in the as-cast alloy. Results indicate that the plastic deformation in the BMG with structure relaxation is accommodated by the semicircular (primary) and radial (secondary) as well as tertiary shear bands. Quantitatively, the shear band density in the relaxed alloy was much lower than that in the as-cast alloy. The annihilation of free volume caused by the annealing was responsible for the embrittlement of the sample with structure relaxation.
