Embrittlement in CN3MN Grade Superaustenitic Stainless Steels
BASKAN, Mertcan; Chumbley, Scott L.; Kalay, Yunus Eren (2014-05-01)
Superaustenitic stainless steels (SSS) are widely used in extreme environments such as off-shore oil wells, chemical and food processing equipment, and seawater systems due to their excellent corrosion resistance and superior toughness. The design of the corresponding heat treatment process is crucial to create better mechanical properties. In this respect, the short-term annealing behavior of CN3MN grade SSS was investigated by a combined study of Charpy impact tests, hardness measurements, scanning and tr...
Perturbation analysis of sheath evolution, with application to plasma source ion implantation
Bektursunova, RM; Demokan, O (IOP Publishing, 2001-02-07)
A perturbation model has been developed to describe the evolution of an expanding plasma sheath around a cathode after a high-voltage negative pulse is applied to the cathode, simulating the conditions in devices such as those used for plasma source ion implantation. The set of governing equations consists of two coupled collisionless fluid equations for ions, and Poisson's equation and Boltzmann's assumption for electrons. The time-dependent, self-consistent expressions for the potential, ion density and i...

Pervaporation of ethanol/water mixtures by zeolite A membranes synthesized in batch and flow systems
Arıcan Yüksel, Berna; Çulfaz, Ali; Kalıpçılar, Halil; Department of Chemical Engineering (2011)
Zeolite A membranes have great potential in pervaporation separation of ethanol/water mixtures with high flux and selectivity. Zeolite membranes usually synthesized from hydrogels in batch systems. In recent years, zeolite membranes are prepared in semicontinuous, continuous and recirculating flow systems to allow the synthesis of zeolite membranes with enlarged surface areas and to overcome the limitations of batch system at industrial level production. The purpose of this study is to develop a synthesis m...

Poly(2-vinylpyridine) is known to be hydrophobic, and a membrane prepared from it would not permeate water-soluble substances in aqueous media. By introducing hydrophilic poly(2-vinyl-N-methylpyridinium iodide) particles into the membrane, it would be possible to control permeation. This type of membrane was prepared and an increase in permeability was observed on increasing the amount of hydrophilic component in the membrane and decreasing the crosslink density of the hydrogel part. The size of the hydroge...
