Decorative composite Layers
(Universitatea "Dunărea de Jos" din Galați, 2008)
Part of the materials used in the chemical industry, metallurgical, machine
construction, can be coated, as with time it occurs either a decrease of its
properties, or even a process of advanced faulting, because of the ...
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 ...
The Influence of Cold Rolling on the Microstructure for Drawing Steels
(Universitatea "Dunărea de Jos" din Galați, 2007)
The paper presents the structural changes that appeared in steel for deep
drawing, as a result of cold rolling and of recrystallization thermal treatment. The
research was conducted on samples taken from the rolled strap, ...
Severe Plastic Deformation an Advanced Method for Nanostructuring Shape Memory Alloys
(Universitatea "Dunărea de Jos" din Galați, 2007)
Severe plastic deformation (SPD) is an advanced plastic deformation. In this
process nanostructuring metals and alloys may be produced. Nanostructured shape
memory alloys are associate with a very high strength, toughness, ...
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 ...
The Influence of Steam Treatment on Mechanical Properties and Abrasive Wear Behavior of Sintered P/M Steels
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
In this paper is a study of the influence of steam treatment on sintered P/M
steels, for three different types of powder. The abrasive wear of steam-treated
sintered iron is analysed by abrasion tests. The specimens were ...
Research in industrial trials to Improve Through-Thickness Z35 Properties of Hot Rolled Heavy plates up to 60 MM Thickness for Structural Steels
(Universitatea "Dunărea de Jos" din Galați, 2016)
The main purpose of this industrial experimental rolling, done in
ArcelorMittal Galati in the Heavy Plate Mill is to check the correlation between
mechanical properties and the microstructure of chemical compositions ...
Industrial Research in Thicker Heavy Plates (70-80 MM) HSLA Steel Micro-Alloyed with Mo-NB-Ti Thermo-Mechanical Control Process in ArcelorMittal Galati
(Universitatea "Dunărea de Jos" din Galați, 2016)
Thermomechanical rolling (TMR or TMCP) is a special rolling process
resulting in an extremely high-strength, fine-grained substructure which
simultaneously offers very good toughness and cold formability. TM products ...
