The effect of cracks on stress state in crane wheel hard-surface under contact loading
(Univ Osijek, Tech Fac, Slavonski Brod, 2017)
Shown in this paper are the results of microstructure testing of crane wheels, along with the repair welding procedure performed by hard-surfacing. Repair welding involved the application of a welded layer to the crane ...
Characterization of a coating 316l applied by plasma transferred arc
(Savez hemijskih inženjera, Beograd, 2018)
Parts of industrial machines and structures are often exposed to the action of aggressive environments, which in a short period of time can provoke the loss of their integrity. It is well known that for extending the service ...
Influence of Friction Welding Parameters on Properties of the Al-Cu Joint
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2017)
In this paper is presented a theoretical-experimental analysis of the aluminum-copper joining by friction welding. Considering that such Al-Cu bimetal joints are widely applied in industrial practice, experimental analysis ...
Microstructure and fracture mode of unalloyed dual-phase austempered ductile iron
(Savez hemijskih inženjera, Beograd, 2022)
Dual-phase ADI material microstructure consists of different amounts and morphologies of ausferrite and free ferrite, obtained by subjecting ductile iron to specific heat treatment. Its strength is lower compared to ...
Effect of plasma hardfacing and carbides presence on the occurrence of cracks and microcracks
(Institut za ispitivanje materijala, Beograd, 2018)
Presented is the effect of plasma hardfacing (or just hardfacing) and carbides presence on the occurrence of cracks and microcracks in the welded layer. The reasons behind this phenomenon are analysed and explained. In ...
External atmospheric influences on the mechanical properties of resin-bonded grinding wheels with aluminium oxide and silicon carbide grains
(Institut za ispitivanje materijala, Beograd, 2020)
Ageing effects on resin-bonded grinding wheel properties are presented, including aluminium oxide and silicon carbide influence. Furthermore, humidity is examined as the most likely cause of significant downgrade in ...
Effect of microstructure on tensile properties of austenite-ferrite welded joint
(Faculty of Metallurgy, 2015)
Complex microstructure of austenite-ferrite welded joint has been investigated, focused on its influence on Focal tensile properties. Tensile properties (yield strength and hardening coefficient) have been evaluated by ...
Material characterization of the main steam gate valve made of X20CrMoV 12.1 steel after long term service
(Elsevier Science Bv, Amsterdam, 2014)
Martensitic steel X20CrMo12.1 has been extensively used within the last few decades as a material for tubing systems and pipelines in thermal power plants (TPP). Long term behavior of this steel is very well known and ...
Mehanička obrada pikosekundnim laserom osnovnog materijala i zavarenih spojeva legure Nimonik 263 / Picosecond laser shock peening of base Nimonic 263 material and laser welded Nimonic 263 alloy
(DUZS - Društvo za unapređivanje zavarivanja u Srbiji, Beograd, 2015)
Lasersko zavarivanje je proces zavarivanja sa velikom gustinom energije i mnogobrojnim prednostima u odnosu na konvencionalne metode zavarivanja (uska zona uticaja toplote, manji unos toplote, manja distorzija i sl.) ...
Selection of the most appropriate welding technology for hardfacing of bucket teeth
(Institute of Metals Technology, 2015)
A possibility of extending the service life of the working parts of construction machinery with particular attention to hardfacing of loader bucket teeth was investigated. In the first part of this paper the tribological ...
