Microstructural changes of Nimonic-263 superalloy caused by laser beam action
(IOP Publishing Ltd, Bristol, 2012)
Pulsed laser treatments induce changes in the microstructure of materials. We have exposed the Nimonic-263 superalloy to pulsed laser beams of various repetition rates and wavelengths and investigated the changes in ...
High reflectance as desired property of shining surface and undesired for laser welding in jewel production of 585 gold alloy
(Metalurgia International, 2013)
For most of golden jewels the desired property is the shining surface. From the other point of view, high level of shining leads to great reflectance of impinged beams from a surface. It means that when a laser beam is ...
Process of generating of quality solution of the oil gear pump which is leading to effectively high performance product
(Technics Technologies Education Management, 2012)
The paper is presented the basis of a procedural character of the generating of new products like hydraulic units with high quality and performance. The oil gear pump is present in various hydraulic systems that can be ...
Impact Toughness of Friction Stir Welded Al-Mg Alloy
(Carl Hanser Verlag, Munich, 2014)
Al-Mg 5083 alloy was friction stir welded by varying welding variables, i.e., rotational speed, traversal speed and tool tilt angle. Welded specimens have been tested by the instrumented Charpy test to evaluate total ...
Belgrade solid waste management optimization potential of landfill gas recovery
(Gh Asachi Technical Univ Iasi, Iasi, 2015)
Establishing a management system for collecting and disposing the solid waste materials is of great importance in urban areas. Belgrade, the capital city of Serbia, is at its initial phase of managing this problem. Currently, ...
Distortion of the substructure of a 20-ft shipping container exposed to zinc hot-dip galvanizing
(Institute of Metals and Technology, 2013)
The main goal of this study was to build a model for a numerical simulation of hot-dip galvanizing of a 20-ft ISO shipping container. For that purpose, the basic transient thermo-mechanical problem of a steel structure ...
Analysis of optimal production program in metalworing industry
(Metalurgia International, 2012)
This paper investigates the effects of the manner of calculating the product cost price on forming the impact criteria in production program optimization in metal working companies by means of genetic algorithms. An algorithm ...
Information-communication and documentation flow within R&D function model
(Technics Technologies Education Management, 2012)
Nowdays, R&D function is being treated as strategic one, in any given system. This fact determines method for its introduction into the system, through "top-down" principle. Since knowledge is not a category reserved for ...
Experimental investigation of rockwool insulation hygrothermal properties related to material structure
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2015)
The hygrothermal properties related to rockwool insulation material structure with different additives are presented using rockwool insulation products obtained from row material of southern Serbia (Vranje region) in the ...
Selection of the most appropriate welding technology for hardfacing of bucket teeth
(Institute of Metals Technology, 2015)
A possibility of extending the service life of the working parts of construction machinery with particular attention to hardfacing of loader bucket teeth was investigated. In the first part of this paper the tribological ...
