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 ...
The standard processing window of alloyed ADI materials
(Kovove Materialy, 2012)
In present paper the effect of austempering conditions and alloying elements on the microstructure, mechanical properties and processing window of Cu and Cu + Ni alloyed austempered ductile irons has been studied. A new ...
Impact Toughness of Friction Stir Welded Al-Mg Alloy
(Carl Hanser Verlag, Munich, 2014)
Al-Mg 5083 alloy was friction stir welded by varying welding variables, i.e., rotational speed, traversal speed and tool tilt angle. Welded specimens have been tested by the instrumented Charpy test to evaluate total ...
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 ...
Austempering Kinetics of Cu-Ni Alloyed Austempered Ductile Iron
(Korean Inst Metals Materials, Seoul, 2014)
The aim of the paper was to investigate the effect of austempering parameters (time and temperature) on the microstructure and mechanical properties of ADI alloyed with 1.5% Cu and 1.6% Ni (in wt.%) in order to establish ...
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.) ...
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 ...
The Effect of Vanadium Content on Microstructure and Impact Toughness of Forged High Alloy Steel X96CrMo12-1
(Springer International Publishing Ag, Cham, 2019)
The aim of this research was to examine the influence of vanadium on the structure and impact toughness of the forged high alloy steel X96CrMo12-1. It is known that vanadium affects the process of solidification of this ...
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 ...
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 ...
