Stress state effect on dynamic strain aging and surface markings during stretching of AlMg7 alloy sheet
(Trans Tech Publications Ltd., 1998)
Stress state effect on dynamic strain aging (DSA) and the related surface appearance was analyzed in uniaxial and biaxial room temperature stretching of AlMg7 alloy sheet. In uniaxial tension the serrated yielding was found ...
Temperature dependent oxygen electrochemistry on platinum low index single crystal surfaces in acid solutions
(Natl Research Council Canada, Ottawa, 1997)
Using the rotating ring-disk technique (RRDPt(hkl)E), the oxygen-reduction reaction (ORR) was studied in sulfuric acid solution over the temperature range 298-333 K. At the same temperature, the exchange current density ...
Mathematical modelling and simulation of drawing thin glass sheet from a rectangular preform
(Glass Technology, 1998)
A mathematical model of thin glass sheet drawing has been developed This model includes momentum, heat and mass balance equations The density, viscosity and specific heat of the glass were calculated as functions of ...
Electrical resistance of cotton-metal fibre yarns
(Inst Chemical Fibres, Lodz, 1999)
Yarns representing cotton-metal fibre blends were studied. The electrical resistance of yarns including different fractions of cotton and metal fibres was compared with cotton yarns having the same nominal characteristics. ...
Corrosion behaviour of epoxy coatings electrodeposited on steel electrochemically modified by Zn-Ni alloy
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
The corrosion behaviour and thermal stability of epoxy coatings electrodeposited on steel: phosphatised steel and steel previously modified by electrodeposited Zn-Ni alloy was investigated during exposure to 3% NaCl. The ...
Study of thermal stability of epoxy coatings electrodeposited on different substrates
(Elsevier Sci Ltd, Oxford, 1999)
The thermal stability of epoxy coatings electrodeposited on steel, phosphatized steel, steel electrochemically modified by Zn-Ni alloys and aluminium has been investigated. Epoxy coatings were formed by cathodic electrodeposition ...
Microstructural characteristics of calcium hydroxyapatite/poly-L-lactide based composites
(Wiley, Hoboken, 1999)
Besides its high osteoinductive properties, hydroxyapatite (HAp) exhibits a relatively low mechanical strength. In order to improve the mechanical properties and reliability of HAp based composites, the addition of selected ...
Modeling of nanostructural design of ultrafine mullite powder particles obtained by ultrasonic spray pyrolysis
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
In this paper, a model of substructure design of mullite powder particles obtained by spray pyrolysis lit the field of ultrasound excitation is described. Based an this model, the size of subparticles (nanoparticles) ...
