Osvajanje tehnologije zavarivanja dvoslojnih Cr-Mo-Ni čelika visoke čvrstoće / Development of welding technology for high strength dual hardness Cr-Mo-Ni steel
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2008)
Višeslojni metalni materijali su nastali kao rezultat specifičnih potreba ili sa ciljem dobijanja kvalitetnog, a jeftinijeg materijala. Posebnu grupu čine višeslojni čelici, koji su našli primenu za izradu sečiva u grafičkoj ...
Residual life estimation of a thermal power plant component: The high-pressure turbine housing case
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2009)
This study focuses on the estimation of residual life of damaged thermal power plant components. The high-pressure turbine housing was chosen as an example of thermal power plant component where, during the years of ...
Investigation of the optimal parameters for repair welding of the coal mill in the fossil power station
(Welding in the World, 2008)
As a part of the coal fired power stations a coal milling plant is important, as it supplies a coal and air mixture for combustion in a power plant. Coal milling plant is involved in wearing process, since the raw coal is ...
Welded joints behaviour in service with special reference to pressure equipment
(Springer, Dordrecht, 2009)
Quality and structural integrity of welded pressure equipment are defined by The Pressure Equipment Directive (97/23/EC). The problem is complex, due to welded joint imperfections, matching effect, heterogeneity of ...
An analysis of the influence of weldment heterogeneity in ferrite-austenite welded structure
(Welding in the World, 2009)
An analysis of the influence of heterogeneity of the ferriteaustenite welded joint on its integrity has been performed. The Charpy specimens, with notch positioned in different regions of welded joint, have been tested ...
Recycling of waste coal dust for the energy-efficient fabrication of bricks: A laboratory to industrial-scale study
(Elsevier, Amsterdam, 2021)
In this study, an optimal mixture of loess brick clays and waste coal dust in laboratory hollow blocks production is determined with the aim of promoting sustainable development in terms of saving resources and energy. The ...
