Static recrystallization is a method of tailoring the microstructure and mechanical properties steels, which important for microalloyed forging steels as hot deformation process significantly affects their properties. In this paper, static behavior low-carbon Nb-V-microalloyed steel was investigated by double-pass compression tests at temperature 800–1100 °C interruption time 1–1000 s. The frac...

Abstract To achieve a desired microstructure and minimize the thickness variation in rolled foils, researchers must understand effects of foil fabrication process variables on evolution. We developed an integrated simulation deformation recrystallization that employs finite element method (FEM) kinetic Monte Carlo (KMC) Potts model, respectively, to investigate evolution during multiple-pass ho...

the in vitro dissolution of plasma-sprayed hydroxyapatite (pha) coatings with different characteristics, produced by various spraying conditions, in a tris-buffered solution at ph 7.4 was experimentally studied through the measurement of calcium ions release with inductively coupled plasma atomic emission spectroscopy (icp-aes), and then modeled. three coating characteristics, the crystallinity...

Determination of critical points on hot stress-strain curve of metals is crucial in thermo-mechanical processes design. In this investigation a mathematical modeling is given to illustrate the behavior of metal during hot deformation processes such as hot rolling. The critical strain for the onset of dynamic recrystallization has been obtained as a function of strain at the maximum stress. In a...

The effects of carbon content on the dynamic and static softening mechanisms of Ti microalloy steels were investigated both in ferrite and austenite regions. &#10The results obtained showed that recrystallization rate decreased as the percentage of carbon content was increased from 0.0035 to 0.110. This is due to the Ti(CN) and TiC precipitates and also the free carbon content. In the ferrite r...

The separation technique of acidbase extraction was used to separate three unknown dye compounds that had different pH from the mixture. The identification of the unknown dyes compounds was performed based on the color of the dyes. Methyl Orange, a common dye, was synthesized and purified by recrystallization. The effectiveness of recrystallization was determined by calculating the percentage r...

Antifreeze (glyco) proteins AF(G)Ps are potent ice recrystallization inhibitors, which is a desirable property to enhance cryopreservation of donor tissue/cells. Here we present the rational synthesis of a new, biomimetic, ice-recrystallization inhibiting polymer derived from a cheap commodity polymer, based on an ampholyte structure. The polymer is used to enhance the cryopreservation of red b...

The S-layer of Caulobacter is a two-dimensional paracrystalline array on the cell surface composed of a single protein, RsaA. We have established conditions for preparation of stable, soluble protein and then efficient in vitro recrystallization of the purified protein. Efficient recrystallization and long range order could not be obtained with pure protein only, though it was apparent that cal...
