The Assessing of Mechanical Characteristics of the Steel Sheets Designed for Drawing for a Five-Month-Period as an Effect of Natural Ageing
(Universitatea "Dunărea de Jos" din Galați, 2009)
In the paper it is presented a study run on a five-month-period regarding the
changes in the mechanical characteristics due to natural ageing for a drawing steel,
cold rolled, unalloyed with 0.04% C. The ageing tendency ...
Characterization of Iron and Low Alloy Steel Powders Obtain by Water Atomization
(Univerversitatea "Dunărea de Jos" din Galați, 2009)
Three types of iron and low ally steel powders were investigated to
determinate their physical properties and surface morphology by SEM analysis. The
powders were obtained by water atomization. The first type of powder ...
Characterization of Thick Hard Layers with ni-Cr-B-Fe-Al Alloy Obtained by Laser Cladding
(Universitatea "Dunărea de Jos" din Galați, 2009)
To increase the resistance to wear and corrosion of the surface layers made
from steel with 0.45% C, multilayer deposition was tested by injection of powder
with chemical composition of 8.9% Cr, 4.5% Fe, 5.1% B, 2, 4% ...
EDX Analysis of Laser Cladding Layers with Ni-Cr-B-Fe-Al Alloy
(Universitatea "Dunărea de Jos" din Galați, 2009)
Multilayer cladding by injection of powder with 8.9% Cr, 4.5% Fe, 5.1% B,
2.4% Al, 0.6% Cu, Ni rest as chemical composition, in melted bath by a continuous
wave CO2laser connected to x-y-z coordinate table was tested in ...
