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 ...
Leaching properties of secondary lead slag stabilized/solidified with cement and selected additives
(Environment Protection Engineering, 2013)
Sodium lead slag, generated during secondary lead production, is characterized as hazardous waste. The aim of the study was to investigate leaching mechanism and behaviour of lead and arsenic from sodium lead slag previously ...
