These results are well consistent with the thermal analysis discussed in Section 3.3. Hence, it is additionally proven that the present phase-separated MGs show double glass transition, crystallization and melting events during heating. 5. Conclusions
(7)Finally, a double glass transition associated with a liquid–liquid transition has been observed in yttrium–aluminum oxide glasses. (8,9) Here we show that homogeneous (pure) titanium alkoxide liquids exhibit two calorimetric glass transitions of comparable magnitude: that is, a comparable change in heat capacity.
The quaternary Zr-La-Co-Al phase-separated metallic glasses (MGs) are shown to experience double glass transition, crystallization and melting events, which could be regarded as possible model materials to study the glassy transition and structural relaxation behavior of BMGs. 1. Introduction
Jump To A glass transition is the kinetic arrest or freezing out of a diffusive degree of freedom. Translational and rotational molecular diffusion rates are inversely proportional to the macroscopic shear viscosity constituting the primary or α relaxation, with small deviations caused by the inhomogeneous nature of the glassy state.
After several thermal cycles, values of glass transition breadth as high as 90-104°C were obtained, and the evolution from one glass transition regime to two distinct, contiguous glass transition regimes was evident.
Download MS PowerPoint Slide On supercooling a liquid, the viscosity rises rapidly until at the glass transition it vitrifies into an amorphous solid accompanied by a steep drop in the heat capacity. Therefore, a pure homogeneous liquid is not expected to display more than one glass transition.
