The capillary dynamic stability of shaped crystal growth from the melt is analyzed using a mathematical model based on the proposal of axisymmetry of crystal and setup geometry.
Graphite-silicon-graphite samples are considered; the melting of the silicon part and the surface temperature distribution in the melt are analyzed in dependence of lamp defocussing.
The effect of melt memory on the shear-induced nonisothermal crystallization of a low-density polyethylene melt is analyzed with a shear DTA instrument.
The diffusion of solute atoms in the melt is analyzed by considering the nonequilibrium partition coefficient at the solid liquid interface.
Graphite-silicon-graphite samples are considered; the melting of the silicon part and the temperature field in the melt are analyzed in dependence of different parameters, like the radius of the sample and the power distribution among the heaters.
The crystallization processes, cold crystallization and solidification from the melt, are analyzed using a modified isoconversional method to obtain the transformation diagrams: temperature-heating/cooling rate and temperature time.
Chemical composition of residual minerals and quenched partial melts were analyzed using SEM-EDS.
The heat transfer in the asphalt slabs and the heat requirement for the snow melting were analyzed.
Minerals were analyzed with a focused beam and a 15 nA current, whereas melts were analyzed by using a 8 nA current and a beam defocused to 5 20-μm diameter.
Besides, the influences of operation parameters including the fluid temperature, the idling time, the pipe spacing and buried depths on snow melting are analyzed, which are helpful for the next optimal design of snow-melting system.
