Group theoretical formulation of nonsymmetrical systems by the group supermatrix procedure
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
The group supermatrix procedure, developed by Zlokovic for systems with symmetry properties described by groups, can be also applied to systems without symmetry. Transformation of a nonsymmetrical system into a system with ...
Application of two independent measurement techniques for determination of ductile crack growth initiation
(Springer Netherlands, 1999)
Charpy impact testing of the high strength low-alloyed steel has been performed by simultaneously recording two independent signals. The magnetic emission (ME) and potential drop (PD) techniques were used to determine ...
Microstructure and toughness of CuNiMo austempered ductile iron
(Elsevier, Amsterdam, 2004)
The effect of austempering on the microstructure and toughness of nodular cast iron (designated as CuNiMoSG) alloyed with molybdenum, copper, nickel, and manganese has been studied. Light microscopy (LM), scanning electron ...
Crystallographic orientations of Ni3Al-based aluminide
(Elsevier Science Inc, New York, 2000)
Inverse pole figures have been plotted to determine preferred crystallographic orientations in a powder-compacted Ni3Al aluminide prealloyed with Fe, Ti and B. The main textural components, although weak, were noticeably ...
Determination of moist air drying ability using chemical potential of water vapour
(Taylor & Francis Inc, Philadelphia, 1998)
A thermodynamically simple method for calculation of chemical potential of water vapour, contained in the unsaturated moist air used as a drying medium in convective dryers, is developed. The introduced concept enables ...
Austempering study of unalloyed and alloyed ductile irons
(MANEY PUBLISHING, LEEDS, 2010)
Austempered ductile iron (ADI) proved to be an advanced material as it possesses remarkable combination of high strength, ductility and toughness with good wear resistance and machinability. These properties can be achieved ...
Inhibitory Effect of Cerium Salts of Lower Carboxylic Acids on Al-Zn-Mg-Cu Alloy in NaCl Solution
(Electrochemical Soc Inc, Pennington, 2021)
The corrosion behavior of AA7049 aluminum alloy in NaCl solution in the presence of environmentally-friendly corrosion inhibitors (Ce-chloride, Ce-formate, Ce-acetate, and Ce-propionate) was analyzed. The chemical composition ...
Failure analysis of the end eye connection of the bucket wheel excavator portal tie-rod support
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
This paper describes the failure analysis results of the bucket wheel excavator (BWE) portal tie-rod support. The results of finite elements analysis (FEA) point out the occurrence of pronounced stress concentration, whereby ...
Variable Coefficients Model for Drying Processes with Conductive Heat Supply
(Taylor & Francis Inc, Philadelphia, 2009)
The proposed model is for heat and mass transfer inside a layer of moist material placed on hot isothermal surface. The relevant thermophysical properties of the material are considered as fully dependent on local temperature ...
Stabilizacija karakteristika gasnih odvodnika prenapona primenom jonizujućeg zračenja / Stabilization of gas-filled surge arrester's characteristics by use of ionizing radiation
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2012)
U radu se razmatra stabilizacija električnog pražnjenja u gasovima primenom spoljašnjeg jonizujućeg zračenja. Razmatrano je pražnjenje modela gasnog odvodnika prenapona u pasivnom i aktivnom radnom režimu. Korišćen je ...
