Physical and metallurgic changes during the friction welding of high-speed cutting steel and tempered steel
(Faculty of Mechanical Engineering in Slavonski Brod, Faculty of Electrical Engineering in Osijek, Faculty of Civil Engineering in Osijek, 2009)
This paper outlines the basic principles of welding by friction of high-speed cutting steel and tempered steel from the viewpoint of metallurgic processes that are going on in the material. The bases of welding by friction ...
Ocena integriteta cevnog sistema vrelovodnog kotla izloženog koroziji / Integrity assessment of hot-water boiler tubing system exposed to corrosion
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2009)
U cilju izvođenja validne procene integriteta komponenti ugrađenih u industrijska energetska postrojenja neophodno je primeniti metodološki pristup koji obuhvata prikupljanje, sistematizaciju i analizu podataka iz ...
Design update, thermal and fluid dynamic analyses of the EU-HCPB TBM in vertical arrangement
(Elsevier Science Sa, Lausanne, 2009)
In the frame of the activities of the EU Breeder Blanket Programme and of the Test Blanket Working Group of ITER, the Helium Cooled Pebble Bed Test Blanket Module (HCPB TBM) is developed in Forschungszentrum Karlsruhe (FZK) ...
Micromechanical estimates of the critical values of j-integral for the steel of steam pipelines
(Springer, New York, 2009)
We analyze the level of damage to 14MoV63 steel for steam pipelines under the conditions of crack-growth initiation according to the mechanism of ductile fracture. The state of the material after service for about 100,000 ...
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 ...
Analiza prigušenja konstrukcije tipa ljuske od legure titana u poređenju sa konstrukcijom od legure aluminijuma / Analysis of structural damping of titanium alloy shell structures as compared with that of aluminium alloy structures
(Institut za ispitivanje materijala, Beograd, 2009)
U ovom radu se razmatra mehaničko ponašanje konstrukcije od legure titana sa aspekta određivanja osnovnih dinamičkih karakteristika. Analiziran je numerički model za konstrukcije legure titana tipa ljuske (osnovni konačni ...
Microstructure Changes of Nickel-Base Superalloys Induced by Interaction with Femtosecond Laser Beam
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
The investigation was performed on nickel-base superalloys, with nickel being the most influential alloying ingredient. After thermo-mechanical preparation and corresponding processing, femtosecond laser beam machining has ...
