An austempering study of ductile iron alloyed with copper
(Srpsko hemijsko društvo, Beograd, 2005)
Austempered ductile iron (ADI) has proved to be an excellent material as it possesses attractive properties: high strength, ductility and toughness are combined with good wear resistance and machinability. These properties ...
Optimization of elevator regimes of movement
(China Machine Press, Beijing, 2004)
The paper presents the procedure for determining the optimal regimes of movement of the elevator cabin as a function of input values such as: distance that elevator cabin has to pass, acceleration, velocity and jerk of the ...
Nanoscale magnetic Behavior of C-60 thin films in earth magnetic field under polarization light influences
(Taylor & Francis Inc, Philadelphia, 2005)
Magnetic behavior of C-60 thin films in the Earths magnetic field under polarization light influence is presented. Transformation of magnetic field for two fullerene thin films of different thickness is investigated. Two ...
Ductile fracture prediction of steam pipeline steel
(Trans Tech Publications Ltd, Durnten-Zurich, 2006)
Considering the conditions to which steels used for the manufacture of steam pipelines are exposed, the micromechanism of their destruction in exploitation is exclusively the ductile one. In order to make an estimation of ...
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 ...
Wärmeübertrager
(Van Basshuysen/Shäfer (Hrsg.), Vieweg, GWV Fachverlage, Wiesbaden, 2006)
Die im Automobilbau verwendeten Wärmeübertrager zeichnen sich durch einen hohen Wärmeaustauschgrad und kompakte Abmasse aus. Die übertragene Wärmemenge wird durch die Wärmeübergangskoeffizienten an den beteiligten Oberflächen, ...
Uticaj orijentacije vlakana na udarnu žilavost i osobine loma kompozita ugljenična vlakna - epoksi smola / The effect of fiber orientation on impact toughness and fracture properties of carbon fiber-epoxy composite
(Institut za ispitivanje materijala, Beograd, 2002)
Uticaj orijentacije ugljeničnih vlakana u kompozitu sa epoksi matricom na udarnu žilavost i na žilavost loma je eksperimentalno analiziran ispitivanjem Šarpi epruveta sa V zarezom i zarezanih epruveta modifikovanog CT ...
Čelici za armiranje betona / Steels for concrete reinforcement
(Institut za ispitivanje materijala, Beograd, 2005)
Ispitivanje čelika u građevinarstvu danas uključuje obimnu aktivnost koja nije na pravi način prikazana u domaćoj stručnoj literaturi. Ispitivanje je od velikog značaja u slučaju čelika za armiranje betona, jer može doći ...
Uticaj sadržaja ojačavača na udarnu žilavost livenog Al-SiCp metal matričnog kompozita / The effect of reinforcement content on impact toughness of cast Al-SiCP metal matrix composite
(Institut za ispitivanje materijala, Beograd, 2002)
Analiziran je uticaj sadržaja Mg u matrici i zapreminskog udela SiC čestica u metal matričnom kompozitu (MMC) na udarnu žilavost. Livena AlMg legura, sa 3%, 5% i 7% sadržaja Mg korišćena je kao metal matrice. Primenjen je ...
