In a X-ray microcomputed tomography study, active corrosion was induced by galvanostatically corroding steel embedded in cement paste. The results give insight into corrosion product build up, crack formation, leaching of products into the cracks and voids, and differences in morphology of corrosion attack in the case of carbon steel or stainless steel reinforcement. Carbon steel was homogeneously etched away with a homogeneous layer of corrosion products forming at the steel/cement paste interface. For ferritic stainless steel, pits were forming, concentrating the corrosion products locally, which led to more extensive damage on the cement paste cover.


Simulation of equal channel angular pressing applied to produce structures with ultrafine-sized grains
Karpuz, Pinar; Şimşir, Caner; Gür, Cemil Hakan (Inderscience Publishers, 2009-01-01)
Severe plastic deformation methods are of great interest in industrial forming applications, as they give rise to significant refinement in microstructures and improvements in mechanical and physical properties. In the 'equal channel angular pressing (ECAP)', which is the most common method for production of ultrafine grained bulk samples, very high plastic strains are introduced into the bulk material without any change in cross section. In this study, the plastic deformation behaviour of the materials sub...

The effect of coupling of unalloyed Mg and Mg-alloys (AZ91 and WE43) with Ti6Al4V alloy on corrosion and degradation behaviours of produced composites has been investigated in simulated body fluid (SBF) by hydrogen evolution, and surface and electrochemical characterization techniques. Combining of unalloyed Mg with Ti6Al4V intensified galvanic corrosion and catastrophic failure occurred by initiation of microcracks formed by sudden hydrogen gas evolution. In contrast to other composites, Ti6Al4V-AZ91 compo...
Characterization of BPN Pyrotechnic Composition Containing Micro- and Nanometer-Sized Boron Particles
Koc, Suzan; Ulaş, Abdullah; Yilmaz, Nil Ezgi (Wiley, 2015-10-01)
The effect of micro- and nanometer-sized boron particles on boron-potassium nitrate (BPN) ignition composition was investigated in this paper. As a starting point, thermochemical calculations were made to determine the most promising ignition compositions. Both stoichiometric and fuel-rich formulations of BPN were produced to observe the performance variation due to boron content. Particle morphology of boron particles and the surface structure of the ignition compositions were investigated by SEM. The infl...
Determination of the elastic properties of amorphous materials: Case study of alkali-silica reaction gel
Moon, Juhyuk; Speziale, Sergio; Akgül, Çağla; KALKAN, BORA; Clark, Simon M; Monteiro, Paulo JM (Elsevier BV, 2013-12-01)
The gel formed during alkali-silica reaction (ASR) can lead to cracking and deterioration of a concrete structure. The elastic properties of the ASR gel using X-ray absorption and Brillouin spectroscopy measurements are reported. X-ray absorption was used to determine the density of the gel as a function of pressure, and the result yields an isothermal bulk modulus of 33 +/- 2 GPa. Brillouin spectroscopy was applied to measure isentropic bulk (24.9-34.0 GPa) and shear moduli (8.7-10.1 GPa) of the gel. The r...
Anodization of titanium alloys for orthopedic applications
Izmir, Merve; Ercan, Batur (Springer Science and Business Media LLC, 2019-03-01)
In recent years, nanostructured oxide films on titanium alloy surfaces have gained significant interest due to their electrical, catalytic and biological properties. In literature, there is variety of different approaches to fabricate nanostructured oxide films. Among these methods, anodization technique, which allows fine-tuning of oxide film thickness, feature size, topography and chemistry, is one of the most popular approaches to fabricate nanostructured oxide films on titanium alloys, and it has been w...
