“…The strength region below 7.44 GPa corresponds to static mechanical testing. Relatively low electric fields of evaporation are realized due to the presence of the chemically active gas in the He-H 2 imaging mixture [19]. The hydrogen promoted reduction of the evaporation field of the BMG nanotips ensured a substantial drop in the field-induced stresses during high-field testing from 7.44 to 5.11 GPa.…”

“…This value is rather higher than that generally determined by the FIM method of field etching [6,19]. Obviously, one of the reasons for this difference may be relatively low lateral resolution of the FEM in the electron mode.…”

Structure of amorphous alloys ZrTiCuNiBe and ZrTiCuNiAl is studied by means of low-field ion and combined field-emission microscopy. In both alloys the structural heterogeneities of nanometer-scale are clearly revealed. The surface layers formed by field evaporation possess a cellular structure. The cells have polygonal shape with transverse size ranging from 2 nm to 20 nm. It is established that variance of the local energy of field evaporation is of 0%-5% in the cell body. A local minimum of the field evaporation energy is observed within the cell boundaries (intercluster boundaries). In the minimum the depth is measured to be of 0.8 eV.

“…Polycluster structure of MGs of different compositions was revealed by means of high resolution field emission microscopy [3,10,11]. Recently the polycluster structure of Zr 52.5 Ti 5 Cu 17.9 Ni 14.6 Al 10 bulk MG was observed by this method as well [12].…”
