On thermophysical and mechanical properties of glass-forming alloys

Ductility and toughness of cold-rolled metallic glasses

“…From collections of data on mechanical prop-erties of metallic glasses [21,22], the tensile fracture stress of the Al-glass is taken as 1155 MPa and the shear stress as 577 MPa. The ribbon thickness is 20 mm and the fracture angle 45 _ (Fig.…”

Thermodynamic, transport and mechanical properties of amorphous metallic alloys: Relation to the glass transition

“…lic glasses obtained both in ribbon and bulk form with those of selected inorganic glass-formers (selenides, borates, silicates, phosphates). The data have been collected from various sources [4,15,16]. The hardness is taken here as a measure of the strength of the glasses.…”

“…A manifestation of this is that the extensive thermodynamic quantities change on undercooling. Further indication of the sampling of various landscape configurations is that fragile liquids loose entropy faster than strong ones when approaching the glass transition [4].…”

“…The fragility index m for metallic (open symbols[1]) and non-metallic (full symbols[4]) as a function of the ratio Tg/TK. Line computed using Eq.…”

Thermodynamic properties of under-cooled silver melts

“…As a result, deep under-cooling can be obtained [18,19]. When combined with the DSC technique, accurate measurement of the specific heat of the deeply under-cooled melts is realized [20][21][22][23].Studies on the measurement of the specific heat of deep under-cooled metal liquids and alloys have been reported recently [24][25][26][27][28], but the accurate experimental data on the specific heat and related thermodynamic properties of the under-cooled melts are still very scarce, for high-melting metals and alloys in the temperature range above 1200 K in particular. The recent literature covers only the measurements of some pure metals and simple binary alloys.…”
