Deformation of Cu-Pd-P metallic glass under cyclic mechanical load on continous heating

Non-Isothermal Dynamic Mechanical Analysis of Ribbon Metallic Glasses and Its Thermodynamic Description

“…It also agrees with our interpretation that rolled and as-prepared specimens achieve joint minimal energy points near T g (~540 K) [ 28 ]. Amplitude-frequency and phase-frequency modulations, arising at the deformation of amorphous alloys [ 26 , 27 , 28 ], do not sufficiently impact the main decrease tendency of function (7), but some variation for its rate takes place. Change of C and B parameters corresponds quantitatively with the thermodynamic functions (4)–(7) that also testifies about the strong relationship between these values and the deformation conditions of the material.…”

“…The difference in energy dynamics of both alloys (if we compare their B parameters from Table 1 ) causes a relatively earlier fracture of the Cu-based ribbon. However, any comparison of these alloys in an amorphous state is limited by T g of copper-based MG (528 K) [ 27 ].…”

“…As a basement for this investigation, our previous experimental data on DMA of Al- and Cu-based ribbon amorphous alloys (with ~40 μm of thickness and 4.5 mm of width) were chosen [ 26 , 27 , 28 ]. The general conditions for DMA are in the presence of F load .…”
