Hardened Aluminium with Discontinuous Copper Threads
(Universitatea "Dunărea de Jos" din Galați, 2006)
The paper presents the influence of the quantity of discontinuous reinforced
threads on the mechanical characteristics of some samples obtained through
deformation from composite material with metallic matrix.
As a raw ...
Behavior of Welded Joints from Some Stainless Austenite Steel Eypes During Nitriding Process
(Universitatea "Dunărea de Jos" din Galați, 2006)
Researches made on welded and nitrided samples from stainless austenite steel
types show that nitriding thermo chemical treatment can be applied also for
welded joints. As a result of the treatment, a diffusion layer ...
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 ...
Influence of Cooling Oil on the Surface Quality of the Roller Strip
(Universitatea "Dunărea de Jos" din Galaţi, 2014)
The excess of emulsion used in the lamination process leads to the formation
of drops which in the annealing process forms spots of burned emulsion. It was also
shown to cause formation areas with high carbon concentrations ...
