the aim of this study is to investigate the nucleation of new grains by necklacing mechanism during dynamic recrystallization (drx). the material used is 316 stainless steel. in order to modeling the deformation behavior during hot rolling, one-hit compression tests were performed at temperature range of 950-1100 °c with strain rates of 0.01-1s-1. the result shows that at the temperature of 100...

In many cases, due to high surface stress, stress concentration and wear, the metal material starts fail from surface. It is necessary investigate interface evolution characteristics under high-speed collisions for widely used materials. The microstructures strengthening mechanism of Ni balls after with 316 L stainless steel were investigated by a self-designed test system. was found that ultra...

In this paper, how magnetic hysteresis loop and magnetic Barkhausen noise (MBN) measurements can provide non destructive information about the evolution of the microstructure during the annealing of cold rolled low carbon steel sheets is shown. The effect of recovery and recrystallization processes on hysteresis loop and MBN signal measurements is analysed and related to the microstructural cha...

This manuscript studied the effect of counterion on the glass transition and recrystallization behavior of amorphous salts of prazosin. Three amorphous salts of prazosin, namely, prazosin hydrochloride, prazosin mesylate and prazosin tosylate were prepared by spray drying, and characterized by optical-polarized microscopy, differential scanning calorimetry and powder X-ray diffraction. Modulate...

The effects of carbon content on the dynamic and static softening mechanisms of Ti microalloy steels were investigated both in ferrite and austenite regions. The 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 reg...

In the present work, we investigated microstructures and properties of as-sprayed annealed CoMoCrSi coatings. Specifically, treatment at 800 °C resulted in good recrystallization, improved microstructure, enhanced An oxide layer formed on coating surfaces; it was mainly composed nano-sized Cr2O3 micro-sized CoMoO4, could account for increased surface microhardness anti-wear performance particul...

In this work, a high-efficiency photocatalytic BiOCl material with visible light absorption range was successfully prepared by one-pot molecular self-assembly and particle recrystallization method at room temperature. the process of crystal growth, tartaric acid, as structure control agent, gradually transforms stacked two-dimensional nano-sheet-like into hierarchical composed petal-like nano-s...

An object is considered as “chiral” if it is not superimposable on its mirror image. Due to the presence of asymmetric carbon atoms, numerous molecules are chiral but other stereogenic centers provide the asymmetric character of molecular compound (e.g. sulfoxides). Metalorganic complexes can also be asymmetric even if the ligands do not have any stereogenic center. The equimolar mixture of two...
