Welding technology of aluminium alloys using friction stir welding / Tehnologija zavarivanja aluminijumskih legura postupkom zavarivanja trenjem alatom
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2010)
The objective of this paper is a development of welding technology of aluminium alloys by Friction Stir Welding (FSW). FSW is a very modern welding process with a great future use, primarily due to a variety of possible ...
Savremeni čelici - dvojnikovanjem izazvana plastičnost
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2014)
A significant increase in the research activity dedicated to high manganese TWIP steels has occurred during the past few years, motivated by the breakthrough combination of strength and ductility possessed by these alloys. ...
Setup of combined creep crack growth model / Postavke kombinovanog modela razvoja prsline u uslovima puzanja
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2009)
The paper sets up the combined criteria for creep crack growth (CCG) assessment. The CCG model considering influence of creep damage on mechanics of fracture correlates the crack growth rate, damage factor and damage factor ...
Ni alloyed steels for low temperature service / Čelici legirani niklom za rad na niskim temperaturama
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2003)
A metallurgical base of alloying in cryogenic steels is presented in this paper. The common use of these steels is for tanks for liquid gases. Main alloying element is Ni, added in amounts between 2.25 and 9 % due to ...
Influence of heat input on HAZ hardness distribution after surfacing two Q+T steels / Uticaj pogonske energije zavarivanja na raspodelu tvrdoće u ZUT pri navarivanju čelika za poboljšanje
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2002)
The aim of this work was to determine the influence of welding heat input on hardness distribution after SURFACING of two quench+temper steels. The results indicate that variation of heat input can partially provide required ...
Influence of initial state on properties of mma welded 14mov 6 3 steel / Uticaj polaznog stanja na osobine REL zavarenog spoja čelika 14mov 6 3
