Karakterizacija zavarenih spojeva cevi od čelika X20CrMoV121 dobijenih različitim tehnologijama zavarivanja
(International Conference "Power Plants 2016" 23rd – 26st November 2016 Zlatibor, Srbija, 2016)
Toplotno postojani martenzitni čelik X20CrMo12 1 je našao široku primenu na domaćim termoenergetskim (TE) postrojenjima za izradu izlaznih sekcija pregrejača cevnog sistema kotla, kao i debelozidih komponenti kao što su ...
Towards a unified and practical industrial model for prediction of hydrogen embrittlement and damage in steels
(Elsevier Science Bv, Amsterdam, 2016)
Bearing in mind the multiple effects of hydrogen in steels, the specific mechanism of hydrogen embrittlement (HE) is active, depending on the experimental conditions and numerous factors which can be grouped as environmental, ...
Influence of Geometry on Pressure and Velocity Distribution in Packed-bed Methanol Steam Reforming Reactor
(Amer Inst Physics, Melville, 2017)
The main tasks of this research is to propose several changes in the packed bed micro methanol steam reformer geometry in order to ensure its performance. The reformer is an integral part of the existing indirect internal ...
True Stress-strain Curves for HSLA Steel Weldment - Iteration Procedure Based on DIC and FEM
(Elsevier, Amsterdam, 2020)
True stress-strain curves of HSLA steel welded joint regions were estimated by using numerical simulation of strains measured by DIC and special iteration procedure to match the results. Strains were measured at certain ...
