Reduction of production cycle time by optimising production and non-production components of time in the metalworking industry: a case study
(Southern African Inst Industrial Engineering, Pretoria, 2016)
The production cycle (PC) time, as a very important economic indicator of freezing current assets, involves the time needed to manufacture a unit or a series of units, from putting them into production until they are put ...
Two-dimensional numerical analysis of active flow control by steady blowing along foil suction side by different urans turbulence models
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2017)
The effects of active separation control by steady blowing jets were investigated numerically on three different examples: subsonic flow past Aerospatiale A airfoil at 13 degrees angle-of-attack, transonic flow past NACA ...
The influence of temperature on mechanical properties of the base material (BM) and welded joint (WJ) made of steel S690QL
(Faculty of Metallurgy, 2016)
This paper presents the analysis of the influence of temperature on mechanic properties of the base material and welded joints made of high strength steel. The joints were welded on S690QL high strength steel plates using ...
Failure investigation and reparation of a crack on the boom of the bucket wheel excavator ERS 1250 Gacko
(Pergamon-Elsevier Science Ltd, Oxford, 2018)
Bucket wheel excavator ERs 1250 has been in operation for over 30 years in the Grae'anica-Gacko mining basin. It is operating in very hard working conditions due to exploiting very solid material, which has adverse effects ...
Effect of aging on mechanical properties of Al-8Si-8Fe-1.4v/SiCp composites
(Faculty of Metallurgy, 2016)
In this study, Al-8Fe-8Si-1.4V/SiCp composites fabricated by squeeze casting process were age-hardened to Study the influence of heat treatment on mechanical properties, such as hardness, bending strength and modulus of ...
Selection of the optimal hard facing (HF) technology of damaged forging dies based on cooling time t8/5
(Faculty of Metallurgy, 2016)
In exploitation, the forging dies are exposed to heating up to very high temperatures, variable loads: compressive, impact and shear. In this paper, the reparatory hard facing of the damaged forging dies is considered. The ...
Distributed hydrological-hydraulic modeling of the karst polje water balance
(Springer Verlag, 2019)
The paper presents developed 3Dnet-HET, a distributed hydrologic model coupled with the discrete channel network concept for groundwater circulation simulation in the karst environment. The hydrologic part is driven by the ...
The Effect of Vanadium Content on Microstructure and Impact Toughness of Forged High Alloy Steel X96CrMo12-1
(Springer International Publishing Ag, Cham, 2019)
The aim of this research was to examine the influence of vanadium on the structure and impact toughness of the forged high alloy steel X96CrMo12-1. It is known that vanadium affects the process of solidification of this ...
Radionuclide Immobilization by Sorption onto Waste Concrete and Bricks-Experimental Design Methodology
(Springer International Publishing Ag, Cham, 2019)
The utilization of construction and demolition waste materials for the radionuclide immobilization by sorption processes was investigated. Given that the liquid radioactive waste usually has a complex composition and that ...
