Microstructural Evolution of al 1100 Aluminum Subjected to Severe Plastic Deformation
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
The goal of this document is to promote a sequence of bulk-deformation
processes able to produce ultrafine grain and also nanostructured wires with
adequate length to be interesting for processing in metallurgical industry. ...
Performance Management System for purifyng Polluted Industrial Water
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
In this paper we show an integrate system of water management and an
efficient solution that is a floating dock, placed in the harbour area. Water quality
is one of the most important elements for life support and ...
Properties of Slags in the System CaO-MgO-Al2O3-SiO2, Important in Deoxidization and Desulphurization of Low Carbon Aluminium Killed Steels
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
Properties of refing slags belonging to the system CaO-MgO-Al2O3-SiO2 are
important in simultaneous or succesive refinig treatment processes in the ladle and
other refing metalurgical reactors. The efficiency of treatments ...
Increase the Steels Purity cast in Vacuum
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
The need to develop products with special characteristics and high
mechanical properties led to the introduction of plastic deformation of semifinished
materials. Special purpose products are produced from slabs, ...
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 ...
Neutralization of Hazardous Waste in Vitreous Mass of Glass
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
The paper presents studies concerning the neutralization of hazardous waste
containing metal ions by embedding them in vitreous matrix which are chemically
stable materials. The main analysed factors are: chemical ...
The Dental Technology in Art Foundry
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
The paper presents results of a study undertaken to implement the dental
casting technique of small parts characterized by extremely complex drawings of
surfaces and thicknesses reduced specific objects. During the study ...
Influence of Micro Glass Beads Added in PBT Matrix on the Mechanical Properties of Composites
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
This paper presents the influence of adding materials (micros glass spheres)
in a matrix of PBT on several mechanical properties: elasticity modulus, stress at
break , elongation at break, energy at break.
The mechanical ...
Investigation of Corrosion Protection by Chemically Applied Patina on Artistic Bronzes
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
Increase of pollution in recent years, requires monitoring of the corrosion
behavior of artistic bronzes coated with syntetic patina, in urban atmosphere.
This present work aims to investigate the corrosion rezistance ...
The Corrosion Behaviour of Aluminum Alloy 2024-T3 in Acidic Environments
(Universitatea "Dunărea de Jos" din Galaţi, 2012)
This research aimed at analysing the acidic corrosion behavior of aluminum
alloy 2024-T3 commonly used in the aerospace. We study the variation of corrosion
rate with immersion time at different values of H2SO4 concentration ...
