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 f
Describe the process of chromatography and how it is used by scientists. Explain the process of product isolation and Purification of the dehydration of 4-methylcyclohexanol to 4-methylcyclohexene. What rate of crystallization is preferred for a recrystallization ...
Briefly describe the conditions you will observe when you reach the end point of the back-titration. What rate of crystallization is preferred for a recrystallization process? Explain the steps and observations when performing a recrystallization. What do you look for during each step?
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...
3It needs no help from us. Putting it in your fridge will in fact increase the speed of the crystallization (结晶). This will make honey harder or nearly impossible to use. If you haven’t opened your watermelons, then there’s no need to put them in your fridge. Research has shown ...
For high Al content, a nanocrystalline microstructure (fcc α-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 ...
The 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 model is presented ...
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...
