Fracture micromechanisms in overaged 7000 alloy forgings
(Journal of Alloys and Compounds, 2007)
Micromechanisms controlling the fracture damage in 7000 alloy forgings are studied for T73-type heat treatments. Insight into the fracture modes are obtained by varying the microstructural attributes associated with the ...
Influence of H-2-N-2 atmosphere composition and annealing duration on the selective surface oxidation of low-carbon steels
(Corrosion Science, 2006)
The selective surface oxidation of the Ti-stabilized interstitial free (Ti-IF) and dual phase (DP) steel during recrystallization annealing at 820 degrees C under the variety of exposure time and composition of protective ...
Effects of the Ar ions pre-amorphization of Si substrateon interface mixing of Fe/Si bilayers
(Journal of Microscopy, Oxford, 2008)
Ion beam mixing of Fe/Si bilayers, induced by 100 keV (40)Arions at room temperature was investigated. Rutherford backscattering spectroscopy (RBS), atomic force microscopy (AFM), scanning electron microscopy (SEM) and ...
Hydridic, thermodynamic and kinetic properties of Hf2Ni intermetallic phase
(International Journal of Hydrogen Energy, 2009)
The intermetallic compound (HfNi)-Ni-2 was the subject of investigations by several methods. The relative stability was checked by calculating its enthalpy and cohesive properties, using the augmented plane wave plus local ...
Modelling and experimental investigations of thin filmsof Mg phosphorus-doped tungsten bronzes obtainedby ultrasonic spray pyrolysis
(Journal of Microscopy, Oxford, 2008)
In this study, the synthesis of thin films of Mg phosphorus doped tungsten bronzes (MgPTB; MgHPW(12)O(40).29H(2)O) by the self-assembly of nano-structured particles of MgPTB obtained using the ultrasonic spray pyrolysis ...
Damage of Ti-stabilized interstitial free steel by gas corrosion
(Kovove Materialy = Metallic Materials, 2008)
Degradation of Ti-stabilized interstitial free steel and damage of this steel caused by selective oxidation during 60 s of recrystallization annealing at 820 degrees C under the different compositions of protective H(2)-N(2) ...
Synthesis of sillenite-type compounds from zeolite precursors: XRPD and SEM/EDS analyses
(Journal of Optoelectronics and Advanced Materials, 2008)
The paper analyze the possibility of using LTA zeolite as a precursor for obtaining sillenite phase (Bi(12)MO(20), M=Si, Ti, Ge) by hydrothermal synthesis process. The synthesis procedure involves mixing of zeolite (Na-LTA) ...
The role of sol-gel procedure conditions in electrochemical behavior and corrosion stability of Ti/[RuO2-TiO2] anodes
(Materials and Manufacturing Processes, 2005)
Using a sol-gel procedure, RuO2-TiO2 active coatings were formed on a titanium support. The conditions of preparation of the RuO2 and TiO2 sols were investigated and the sols were characterized by transmission electron ...
Hydrogen storage properties of MgH(2)-diatomite composites obtained by high-energy ball milling
(Journal of Microscopy, Oxford, 2008)
To investigate the effects of specific porous microstructure of diatomite on the hydrogen storage properties of MgH(2), a two-step preparation was carried out. The first step was decrepitation of MgH(2) particle size during ...
Hydrogels based on 2-hydroxyethyl methacrylate obtained by gamma irradiation
(Materials Science Forum, 2005)
Hydrogels based on 2-hydroxyethyl methacrylate and different types of poly(alkylene glycol) acrylates and methacrylates, with a small percent of itaconic acid, have been prepared by solution copolymerization using gamma ...
