7000 series Aluminum alloys are widely used in the automotive industries for structural lightweight components due to their exceptional high strength to weight ratio. However, this class of aluminum alloy is difficult to join by conventional fusion welding techniques so Friction stir welding (FSW) widely is used for welding this alloys. The process has been demonstrated to be effective and is c...

The ice recrystallization inhibition activity of various mono- and disaccharides has been correlated with their ability to cryopreserve human cell lines at various concentrations. Cell viabilities after cryopreservation were compared with control experiments where cells were cryopreserved with dimethylsulfoxide (DMSO). The most potent inhibitors of ice recrystallization were 220 mM solutions of...

A crack-free Ti-43Al-9V-0.2Y alloy sheet was successfully fabricated via hot-pack rolling at 1200 °C. After hot-rolling, the β/γ lamellar microstructure of the as-forged TiAl alloy was completely converted into a homogeneous duplex microstructure with an average γ grain size of 10.5 μm. The dynamic recrystallization (DRX) of the γ phase was systematically investigated. A recrystallization fract...

Abstract Silicon carbide layers were fabricated using self-propagating high-temperature synthesis of binary silicon-carbon based reactive multilayers. The silicon and carbon bilayers with two different bilayer thicknesses. They are deposited by magnetron sputtering in an alternating layer system a total thickness 1 μm. entire is annealed rapid thermal annealing at temperatures ranging from 500 ...

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...

This paper describes an investigation into the suitability of Gaussian process models for predicting the microstructure evolution arising from static recrystallization. These methods have the advantage of not requiring a prior understanding of the micromechanical processes. They are wholly empirical and use a Bayesian framework to infer the probability distribution of data, given a ‘training se...

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...
