Procena integriteta feritno-austenitnih zavarenih spojeva / Structural integrity assessment of ferrite-austenitic welded joints
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2008)
Ovaj rad prikazuje uticaj prslina na integritet heterogenih feritno-austenitnih zavarenih spojeva primenom osnovnih principa mehanike loma. Sile rasta prsline su određene numerički primenom Kingove metode, dok je otpornost ...
Transition temperature and fracture mode of as-castand austempered ductile iron
(Wiley, Hoboken, 2008)
The ductile to brittle transition temperature is a very important criterion that is used for selection of materials in some applications, especially in low-temperature conditions. For that reason, in this paper transition ...
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 ...
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 ...
