Quality assurance of storage tanks after in-service crack repairs / Osiguranje kvaliteta rezervoara u eksploataciji posle popravke prslina
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
According to the Pressure Equipment Directive (PED 97/23/EC) a new produced storage tank can be accepted on the market only if the required quality is proved. In this way the structural integrity might be at the requested ...
Structural properties of Co, Ni and Mo powders obtained by electrochemical deposition
(Savez inženjera metalurgije Srbije, Beograd, 2011)
Magnetic thin films based on iron group elements (Fe, Co, Ni) are currently used in computer's hard disk drives and in MEMS, whereas electrodeposition is a suitable method to obtain these materials. The powders of metals ...
The analysis of the tribological properties of multiple strengthened nanocomposite of the Cu-Al2o3 system
(Savez inženjera metalurgije Srbije, Beograd, 2011)
This paper presents the results of examined tribological properties of the multiple strengthened nanocomposite Cu-Al2O3 system. Cu-Al2O3 composite powder was obtained by combination of the thermo-chemical procedure and ...
Modern steels: Transformation induced plasticity / Savremeni čelici - transformacijom izazvana plastičnost
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2011)
TRIP čelici danas zauzimaju značajno mesto u komercijaloj upotrebi u vozilima i konstrukcijama kod kojih je jedan od glavnih zahteva redukcija sopstvene težine. Optimalna kombinacija udela stabilisanog austenita i stepen ...
Application of exergy analysis in recycling streams / Primena eksergijske analize u reciklažnim tokovima
(Engineering Society for Corrosion, Belgrade, Serbia, 2015)
Materials for recycling always contain a certain degree of contamination. The presence of impurities i.e. contamination in the recycling streams causes a change in the composition of the original materials to recycle. As ...
Assessment of pressure vessel load capacity in the presence of cracks / Procena nosivosti posude pod pritiskom u prisustvu prsline
(Society for Structural Integrity and Life, Institute for Material Testing, 2013)
The paper illustrates the structural assessment of an investigated pressure vessel, made of low-alloyed high strength steel, with an external surface crack located on the shell wall. In order to assess the remaining strength ...
