type pieces. The new types of radial forging machines are presented cinematically.
The movement of the deformation tools at these types of ...
Mechanical and Tribological Properties of TiCxOy Thin Films
(Universitatea "Dunărea de Jos" din Galați, 2005)
The main purpose of this work consists on the preparation of single layered
titanium oxycarbide, TiCxOy, thin films, deposited by d.c. reactive magnetron
sputtering. The depositions were carried out from a TiC solid ...
Thermomechanical Processing of Microalloyed Steels Used for Naval and Oil Industries
(Universitatea "Dunărea de Jos" din Galați, 2005)
This paperwork shows the laboratory experiments made on X60 and X65 steels
with several intercritical thermomechanical treatment application.
Two variants were used: “down-up” thermomechanical treatment with heating
and ...
Elastoplastic Model for the Steel Bars Under Thermal Treatments
(Universitatea "Dunarea de Jos" din Galați, 2005)
In order to understand material behavior, during the stresses action produced
by thermal effects of volume, was started from Hooke relations, whereat was added
the expressions that take into account these effects. Have ...
Zinc Layer Removal at the Steel Appliances Scraps
(Universitatea "Dunărea de Jos" din Galați, 2005)
All appliances contain an important quantity of steel and iron. These can be
further recycled at the end of product usefulness. A component of the appliances is
the bodies. These are made from galvanized steel. A study ...
The Influence of the Thermomagnetic Treatments on the Hardness Number of Steels and the Superficial Layers Nitrided Durability
(Univeritatea "Dunărea de Jos" din Galați, 2005)
Two types of steels subjected to a nitriding thermo-chemical treatment after
thermomagnetic treatments. The structural aspects into superficial layer of these
steels are studied during friction process by using of an ...
