Half-Finished Technology of Steels and Fatigue Strength
(Universitatea "Dunărea de Jos" din Galați, 2008)
The paper presents the bending fatigue testing for four steel brands. The test
showed that the fatigue strength is decreasing with the increasing of both ingot size
and the rolled sheet thickness. The fatigue strength ...
Behaviour of Some Important Components in a cold Rolling Mill
(Universitatea "Dunărea de Jos" din Galaţi, 2008)
For a good behaviour of mill parts and accurate functioning it is necessary to
have an integrated system for all mill tandem. It is important to know the speed
controls and strip tension in correlation with torque, ...
Nanostructured Surface for 38MoCrA109 Steel by Nitriding in Nitrogen Atmosphere and Yag;Nd Pulse Laser Activation
(Universitatea "Dunărea de Jos" din Galați, 2008)
YAG:Nd pulse laser is usually used for cutting and welding. The paper is based
by experiments using YAG:Nd pulse laser (KVANT 17-CIS made). Technological
modules were assembled for laser beam deviation and for relative ...
Modelling by Finite Element Analysis Method of Stress State Establishing for an Alloy Steel
(Universitatea "Dunărea de Jos" din Galați, 2008)
The paper presents some results about the tension state in samples subject to
pure bending fatigue process. Numerical simulation based on finite element method
was used. The tension field induced by a vertical deformation ...
Electrodeposition Obtaining and Corrosion Behaviour of Phenol Formaldehyde Resin/Zinc Composite Coatings
(Universitatea "Dunărea de Jos" din Galați, 2008)
The present work has the purpose of obtaining composite coatings in zinc matrix
by using phenol - formaldehyde resin type NOVOLAC (RESITAL 6358/1) in the
electrodeposition process of zinc. The PF resin/Zn composite ...
Laser Surface Alloying of Some Steels from SiC Predeposited Powders
(Universitatea "Dunărea de Jos" din Galați, 2008)
For the purpose of studying the possibilities of increasing the wear resistance,
specimens of three steels with 0.2%C, 0.46%C and 1%C were surface alloyed with
reinforcement from overlapping pastes with green SiC hard ...
Research for Realize the Configuration of Wind Energy Turbine
(Universitatea "Dunărea de Jos" din Galați, 2008)
For already quite some time, the word energy has received a somewhat negative
connotation. Some circles want to make us believe that energy is something that one
should have disgust for; a necessary evil that should be ...
The Modern State of Works in Field of Electron-Beam Technology of Melting and Evaporation of Metals and Non-Metals in a Vacuum
(Universitatea "Dunărea de Jos' din Galați, 2008)
In developing of new processes for growing metal (composite) films, the main
attention is given to controlling the metal vapour flows: through energy state of the
condensing particles, their molecular composition, ...
Structure Effects Over Behavior of Graphite Gray Iron in Running
(Universitatea "Dunărea de Jos" din Galați, 2008)
The work aims at emphasizing the structure changes of graphite gray iron, as a
result of make-casting conditions and their effects over behavior in running of
several cast items. Researches consisted of complex ...
Vaporisation of the Metallic Bath Component During Refining in Oxygen Converter
(Universitatea "Dunărea de Jos" din Galați, 2008)
The paper presents a series of researches regarding the vaporization of the
component elements of the metallic bath and slag during refining in LD converter.
Also, the main factors which influence the vaporization process ...
