The structure and crystallization of silver-doped germano-gallate glasses for substitution potassium barium ions have been investigated. By means Raman spectroscopy, a structural study has carried out revealing glass network depolymerization with the formation non-bridging oxygens likely localized on germanium tetrahedra when concentration increases. These modifications do not appear to signifi...

Achieving extreme hardness in the newly synthetic steel formed by converting from initial amorphous state to subse-quent crystalline structure –named as devitrification process- was studied in this research work. Results of TEM observa-tions and XRD tests showed that crystallized microstructure were made up four different nano-scale phases i.e., α-Fe, Fe 36 Cr12 Mo10 , Fe 3 C and Fe3 B. More, V...

Thin film metallic glasses undergoing devitrification can form partially crystallized or fully materials with novel structural and magnetic properties. The development of desired tunable properties such systems drives the need to understand mechanism their thermal evolution at atomic level. Co-sputtered amorphous Ni-Zr alloy thin films which were thermally annealed in steps 200 deg C from room ...

Abstract This paper focusses on investigating and comparing the congruent crystallization of phosphate glasses with different degrees polymerization. The study was performed both powders, size fractions, coarse particles which can be assimilated to bulk. From DSC experiments, corroborated by SEM analysis, it demonstrated that LiPO3 crystallizes from surface whereas LiGe2(PO4)3 in whole volume. ...
