Uticaj ekvivalentnog sadržaja kiseonika u mešavini gasova na strukturu i žilavost metala šava mikrolegiranih čelika / The influence of the oxygen equivalent in a gas-mixture on the structure and toughness of microalloyed steel weldments
(Srpsko hemijsko društvo, Beograd, 2006)
Ispitivanja su izvedena na dva čelika. Prvi je mikrolegiran sa Nb, a drugi sa: Ti, Nb i V. Žilavost metala šava navedenih čelika je određena na instrumentiranom Šarpijevom klatnu. Pet različitih mešavina gasova (Ar, CO2, ...
Microstructure Changes of Nickel-Base Superalloys Induced by Interaction with Femtosecond Laser Beam
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
The investigation was performed on nickel-base superalloys, with nickel being the most influential alloying ingredient. After thermo-mechanical preparation and corresponding processing, femtosecond laser beam machining has ...
Radiation Absorption Characteristics of Titanium Alloys
(Polish Acad Sciences Inst Physics, Warsaw, 2009)
Titanium alloys have found numerous applications in space research, and nuclear industry and research. Since X-rays constitute an important part of the space radiation environment, numerical simulations of radiation ...
An austempering study of ductile iron alloyed with copper
(Srpsko hemijsko društvo, Beograd, 2005)
Austempered ductile iron (ADI) has proved to be an excellent material as it possesses attractive properties: high strength, ductility and toughness are combined with good wear resistance and machinability. These properties ...
Damage Level Estimate of API J55 Steel for Welded Seam Casing Pipes
(Croation Union of Mech. Engineers and Naval Architects, 2009)
The subject of this paper is investigation of the damage level of API J55 steel, used for manufacturing casing pipes by high frequency (HF) contact welding. The analysed pipe was withdrawn after about 70 000 hours of service ...
