This work is concerned with some new formal relationships between α ex and α, which describe the process of crystallization. Besides Avrami's relationship α ex = − ln(1t-α), relationships of the general form are also considered. The values of α max, corresponding to the maximum ...
Derivation of a langmuir type of model to describe the intrinsic growth rate of gas hydrates during crystallization from gas mixtures. Chemical Engineering Science. 2012; 81: p. 28 - 37.Herri JM, Kwaterski M. Derivation of a Langmuir type of model to describe the intrinsic growth rate of ...
The objective, company president Michael Wittmann said, is for the TCU to continuously compare the set-point temperature of a process with the actual temperature and adjust operations accordingly. A machine running too hot would be cooled down, and auxiliary units like the robot and conveying line...
The predictions of the analysis have been used to describe the crystallization process of two amorphous alloys with Fe90Zr10 and (Fe0.7Co0.3)Zr-10 composition, respectively, which consists of two overlapped processes ascribed to the formation of alpha-Fe(Co) phase and a Zr-rich intermetallic. ...
Finally, their changes versus crystalline fraction provide relevant information to describe the nanocrystallization process occurring during the transformation from the amorphous into the nanocrystalline state in the case of FINEMET alloys.doi:10.1023/A:1010858927701J. M. Borrego...
Crystallization (ModelsThe evolution of the spherulitic morphology, commonly encountered during the solidification of semicrystalline materials, is modeled by taking into account the transport of the solute (the noncrystallizing species) and the crystallization kinetics. In this paper, a microscopic cell ...

For high Al content, a nanocrystalline microstructure (fcc 伪-Al embedded in an amorphous matrix) is formed during the first crystallization process. However, for the alloy with 85 at.% of Al, the devitrification process consists of two strongly overlapped stages, which yield the formation of ...
