Structural transition in liquid cobalt

Structural transitions and nonmonotonic relaxation processes in liquid metals

“…For example, the time dependence of the kinetic viscosity of liquid Co at T = 1600 • C is presented in Fig.1(b). These results were obtained in [8] by the torsional vibrations method in isothermal regime. As usual [8], the temperature was rapidly elevated and maintained at the given level.…”

“…These results were obtained in [8] by the torsional vibrations method in isothermal regime. As usual [8], the temperature was rapidly elevated and maintained at the given level. In the figure one can see considerable fluctuating of the measured quantities of viscosity.…”

On the solidification of the Fe50Cr15Mo14C15B6 bulk-amorphized alloy

“…The quenching of the melt from this temperature area results in an increase of the glass forming ability [11,12] as well as the shape change of the structure and properties of the alloys obtained [13]. At the same time, as shown in [10,14], in the polytherms of the structural-sensitive properties of melts (viscosity, density, etc.) in the vicinity of the given temperatures, different types anomalies are observed.…”

“…This is due to the dependence of the structure formation processes on the structural state of the liquid phase which is inherited to some extent in the solidification process [10]. The melt temperature area which is characterized by the greatest values of supercooling has been found experimentally [11,12].…”

“…Because, during actual viscosity measurements, an increased spread of experimental points may appear, which is directly related to the state of the melt itself, e.g., at temperatures near the melting point [18] or in the region of a structural transformation in the liquid state [24], we calculated the random error of the damping factor at temperatures 350-400°ë higher than the liquidus line after a long (30-60 min) isothermal exposure. Therefore, the random component of damping-factor error Δδ r was calculated from formula (5) as the rms deviation of the damping factor from its average value.…”
