Intragranular ferrite morphologies in medium carbon vanadium-micro alloyed steel
(University of Belgrade, Technical Faculty, Bor, 2013)
The aim of this work was to determine TTT diagram of medium carbon V-N micro-alloyed steel with emphasis on the development of intragranular ferrite morphologies. The isothermal treatment was carried out at 350, 400, 450, ...
Deformation behaviour of two continuously cooled vanadium microalloyed steels at liquid nitrogen temperature / Deformaciono ponašanje dva kontinuirano hlađena vanadijum mikrolegirana čelika na temperaturi tečnog azota
(Association of Chemical Engineers of Serbia, 2013)
The aim of this work was to establish the deformation behavior of two vanadium microalloyed medium carbon steels with different contents of carbon and titanium by tensile testing at 77 K. Samples were reheated at 1250°C ...
A solidification/stabilization process for wastewater treatment sludge from a primary copper smelter / Proces solidifikacije/stabilizacije za tretman otpadnih voda mulja iz primarne topionice bakra
(Serbian Chemical Society, Belgrade, 2013)
Wastewater treatment sludge from a primary copper smelter is characterized as hazardous waste that requires treatment prior to disposal due to its significant contents of heavy metals and arsenic. The aim of the presented ...
