In this research, Glass Form Ability (GFA) has been investigated in the new class of Fe-based amorphous alloys. Indeed, the main purpose is to evaluate the effects of alloying with niobium on glass form ability of Fe55-xCr18Mo7B16C4Nbx (X=0, 3, 4, 5) alloys. Vacuum induction melting (VIM) was utilized for production of primary ingots and melt spinning process was used for production of thin ri...
The thermal expansion coefficient (TEC) of binary glasses SiO 2 -TiO decreases as the TiO concentration grows. At in range 4-6 mol% (in dependence applied synthesis method) TEC becomes negative; at 8-11 devitrification occurs. A combination photoluminescence (PL) and IR reflection techniques were for studying evolution point structural defects from zero to phase separation. precision measuremen...
