Correlation Between the Properties of Old Slags and the Recycling Solutions
(Universitatea "Dunărea de Jos" din Galaţi, 2014)
The blast furnace and basic oxygen furnace route of steel making (from iron
ores and coke to steel) or the so called integrated steel production generates
simultaneously solid waste products. The slag is predominant, ...
Effect of an a Oxy-SulPhide Inoculant Enhancer on Graphite Parameters in the Mould Inoculated Compacted Graphite Cast Iron
(Universitatea "Dunărea de Jos" din Galaţi, 2014)
In compacted/vermicular graphite cast iron production, inoculation is applied
to limit the formation of carbides, but usually this treatment also promotes nodular
graphite with improved nodularity. The main objective of ...
Dynamics of Nutrients in Aquatic Ecosystems: The Case Study of Ciric Basin River at Nord of Iași City
(Universitatea "Dunărea de Jos" din Galați, 2014)
A 1 year dynamics of two biologically limiting nutrients (N and P) has been
carried out in the Ciric basin river at nord of Iasi City. The total nitrogen
concentrations varied from 7.55-17.55 mg N/L and total phosphorus ...
Comparative Characteristics of Martensite and Bainite in Cu-Based SMAs
(Universitatea "Dunărea de Jos" din Galați, 2014)
The present work reports the evolution of micro-structure and shape memory
behavior in a Cu-15 Zn-6 Al (mass. %) shape memory alloy (SMA), as a function of
the applied hot working procedure and of the performed heat ...
The Evolution of the Characteristics of Mechanical Resistance for the Nitro-Carburized Treated Steel, After Thermo-Magnetic Treatment
(Universitatea Dunărea de Jos" din Galaţi, 2014)
The aim of the research was to study the evolution of the characteristics of
mechanical resistance for one type of steel. The material was subjected to the
thermo-chemical (nitro-carburized treatment in plasma) treatment ...
Research on the Work Place Security and Environmental Factors Affected by Lathe Work
(Universitatea "Dunărea de Jos" din Galaţi, 2014)
Most work place risks are spatially and temporally determined, so a critical
early need is to establish the risk of what (is happening) to whom (which part of the
environment is affected), where (location) and when (in ...
Research on the Influence of the Complementary Phase Percentange on the Properties of Copper-Based Composites
(Universitatea "Dunărea de Jos" din Galaţi, 2014)
The article presents the method to obtain copper matrix composite with Cu-
Al-Fe alloy particles as complementary phase. The samples were obtained by
powder metallurgy methods using different percentages of complementary ...
Establishing the Rolling-Friction Coefficient for Different Contacts Between Balls and Termochemicallly Treated Steel Rolling Paths
(Universitatea "Dunărea de Jos" din Galați, 2014)
Within the frame of this work, the influence of four very well-known and often
used thermochemical treatments (carburizing, carbonitriding, nitriding and
nitrocarburizing) of steel rolling paths applied on rolling-friction ...
Structural Changes Associated with the Pseudoelastic Response of Fe-based Shape Memory Alloys
(Universitatea "Dunărea de Jos" din Galați, 2014)
The pseudoelastic responses of two types of iron base shape memory alloys
(SMAs) were introduced and discussed. The former was based on Fe-Mn-Si system,
obtained by classical (CM) and by powder metallurgy (PM) manufacturing. ...
Challenges in Corrosion Protection using Vegetable Extracts as Inhibitors-Electrochemical Studies
(Universitatea "Dunărea de Jos" din Galați, 2014)
Corrosion is an irreversible chemical or electrochemical reaction of a
material with its surrounding environment or medium which results in consumption
of the material or in dissolution into the material of a component ...
