Thermal Decomposition of Hafnium Ethoxide-Mollecular Precursor for Hafnia Dielectric Thin Films
(Universitatea "Dunărea de Jos" din Galați, 2012)
The HfO2 thin-film is a very promising gate dielectric material for last
generation transistors. The paper presents the thermal decomposition of hafnium
ethoxide used as molecular precursor for obtaining hafnia thin ...
Behavior of Refractories in Interaction with Metallurgical Slag
(Universitatea "Dunărea de Jos" din Galați, 2012)
The aim of this paper is to present the studies concerning behavior of the
refractory to metallurgical slag corrosion. The corrosion resistance at high
temperatures using the static method on samples containing chamotte ...
An Isothermal Model for Evaluating Stress and Strain in the Polymeric Block of the Block-on-Ring System
(Universitatea "Dunărea de Jos" din Galați, 2012)
This paper presents the results of simulating an isothermal frictional contact
between a polymeric block and a steel ring. The model takes into account the
elasto-plastic behavior of the polymeric materials and the ...
Research on the Production of Sintered Powder 316
(Universitatea "Dunărea de Jos" din Galați, 2012)
The 316 austenitic stainless steel powders are typically used in applications
requiring good corrosion resistance, mechanical strength at high and very low
temperatures, good ductility, wear resistance, associated in ...

Mechanical properties and Abrasive Wear Behavior of Fluidized-bed Carburized Sintered Iron Alloys
(Universitatea "Dunărea de Jos" din Galați, 2012)
This paper is a study of the influence of fluidized bed carburizing of sintered
steels on the mechanical properties and the abrasive wear behavior for two
different types of powder. Carburizing was carried out at a ...
Increase of Converter Life by Own Slag Coating
(Universitatea "Dunărea de Jos" din Galați, 2012)
This paper presents a method for the improvement of the lining life of the BOF
converter by slag coating, under nitrogen pressure. Own slag coating of converter
lining is put in practice after steel tapping. Dolomite ...
Improvement of Casting Technology by Using of Exothermic Feeder Head and Simulation the Solidification Alloy

This paper presents a simulation program use of feeders exothermic and
insulating plates. High quality casting is considerably improved by using
solidification simulation flow and cast.
Measurement and Analysis of Vibrations on a Cold Rolling Mill for Steel Strip
(Universitatea "Dunărea de Jos" din Galați, 2012)
In this paper the authors made measurements and registration of vibration by
using accelerometers posted on the top backup rolls. This is a new way for predict
the damage in the rolling mill equipment and the precision ...
