Long-term and low-temperature annealing of as-continuous drive friction welded and post-weld heat treated Al/Cu bimetal joints
(Kiev, Ukraine, 2017)
In general, continuous drive friction welding (CDFW) of two metals
may produce three typical regions from a weld interface towards an unaf-
fected base metal: (i) fully deformed or dynamically recrystallized (DRX) ...
The effects of aging on the precipitation of the W-rich phase in the matrix of the 92.5W-5Ni-2,5Fe powder metallurgy heavy alloys
(Association of Metallurgical Engineers of Serbia (AMES), Beograd, 2013)
The precipitation behavior of W-rich phase on the specific matrix locations of
Co-free and Co-containing 92.5W-5Ni-2.5Fe heavy alloys is investigated during
aging of the as-quenched samples. The aging treatment is ...
Walsh analysis - a convenient preprocessor for period detection in astronomy
(Astronomical Observatory Belgrade, 2016)
Walsh analysis is practically analogous to Fourier analysis, except that square wave is used instead of the sine one. It has one major advantage over Fourier - it can be performed much faster. This may seem of little ...
Određivanje veštačkog zaslađivača saharina u uzorcima otpadne vode / Determination of artificial sweetener saccharin in wastewater samples
(Beograd : Beogradska politehnika, 2019)
Široka primena veštačkih zaslađivača u prehrambenoj i farmaceutskoj industriji počela je početkom osamdesetih godina prošlog veka. Većina ovih jedinjenja se ne metaboliše u ljudskom telu i izlučuje se uglavnom nepromenjena. ...
