Opis:: Strain recovery measurements under linear heating for Fe- and Co-based metallic glasses during axial tension of the hydrided crystalline Ni are presented. Using the mechanical, exoelectron emission and X-ray analysis methods the temperature of a start of high-rate strain recovery in metallic glasses was determined. The important role of the surface layer in the strains recovery processes of crystalline-Ni was shown.

Opis:: The results of the investigations of thermally stimulated electron emission from graphite submitted to intercalation of K-Bi alloy, in the temperature range of 100-400 K, are presented. Total and partial pressure in the measuring chamber in relation to the temperature of the sample are also reported. The insertion of a K-Bi alloy into the interlayers of graphite considerably changes thermally stimulated electron emission properties. The emission images I(T) depend on the content of intercalate and the emission maxima obtained at temperatures of about 170 and 210 K are conditioned by the desorption of a gas while the total pressure above the different samples is of the same order. The desorption of gases at a temperature over 250 K does not cause any increase in the electron emission.

Opis:: The aim of this work was the evaluation of ion-beam induced luminescence for the characterization of luminescent oxide materials containing rare earth elements. The yttrium aluminium garnet epilayers doped with Nd, Pr, Ho, and Tm atoms were used. The ion-beam induced luminescence spectra were excited using 100 keV $H_2^{+}$ ion beam and were recorded in the wavelengths ranging from 300 nm up to 1000 nm. The separate parts of the surface of the same samples were used for ion-beam induced luminescence and cathodoluminescence experiments. Cathodoluminescence spectra have been recorded in the range from 370 nm up to 850 nm at 20 keV e-beam in scanning electron microscope equipped with a grating spectrometer coupled with a photomultiplier. The observed narrow ion-beam induced luminescence lines can be ascribed to the well known radiative transitions in the rare-earth ions in the YAG crystals. The cathodoluminescence spectra reveal essentially the same emission lines as ion-beam induced luminescence. The decrease of the ion-beam induced luminescence lines intensity has been observed under the increasing ion fluences. The ion-beam induced luminescence may be used for characterization of transparent luminescent materials as an alternative method for cathodoluminescence and can be especially useful for observation of ion-beam damage formation in crystals.
