Room temperature deformation behaviour of A1Mg6.5 alloy sheet
(Carl Hanser Verlag, Munich, 1999)
Room temperature tensile test have been performed with initial strain rates of 6.7 x 10(-4) s(-1), 6.7 x 10(-3) s-(1) and 6.7 x 10(-2) s(-1), on AlMg6.5 alloy sheet, after imposing 5% to 70% cold rolling reductions, and ...
Thermal investigation of some chelate Ni(II) complexes
(Serbian Chemical Society, Belgrade, 1999)
Several diamine-nickel(II) complexes have been prepared and the kinetic parameters of their decomposition reactions investigated. The complexes undergo a gradual thermal decomposition. First, water is lost, followed by the ...
A Study of the Mn, Co and Ni Environment in the As-synthesized and Rehydrated-calcined Aluminophosphate with Chabazite-like Topology
(Croatian Chemical Society, 1999)
Diffuse-reflectance spectroscopy (DRS), X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) methods are applied to an investigation of Mn, Co and Ni local environments in MnAlPO, ...
Multiaxial determination of the resistance to creasing of clothing wool fabrics
(Emerald Group Publishing Limited, Bradford, 1999)
In this paper, values of deformation components (elastic, viscoelastic, plastic) of clothing wool fabrics by measuring the crease recovery angle in various directions to the warp direction (0°-warp, 30°, 45°, 60°, and ...
Benzylation of N-benzyl-2-phenylacetamide
(Serbian Chemical Society, Belgrade, 1999)
N-Benzyl-2-phenylacetamide was used as a model for the study of the alkylation of N-substituted 2-phenylacetamides with benzyl chloride in the presence of powdered KOH. The reactions were carried out in the presence and ...
Thermal shock behavior of alumina based refractories: fracture resistance parameters and water quench test
(Elsevier, Amsterdam, 1999)
The prediction of refractories thermal shock behavior can be estimated on two basis: heat transfer conditions and/or fracture mechanics concept. Materials considered in our analysis were alumina based refractories with ...
Resistance parameters and water quench test as criteria of thermal shock behaviour of alumina based refractories
(Taylor & Francis Ltd, Abingdon, 1999)
The materials investigated were five alumina based commercial refractories with different contents of Al2O3 + TiO2 from 28 to 78%. Thermal (k thermal conductivity, alpha coefficient of thermal expansion) and mechanical (E ...
Electron microscopy observations of twin-twin intersections in a particle hardened copper-titanium alloy
(Scripta Materialia, 1999)
The twin-twin intersections in the precipitation hardened two-phase copper-titanium alloys were studied using conventional and high-resolution electron microscopy. The incident twin propagation through an obstacle twin was ...
