U ovom radu je istraživana mogućnost dobijanja novih vatrostalnih premaza na bazi cirkona koji bi imali primenu u livarstvu. Optimizacija sastava premaza kontrolisana reološkim svojstvima postignuta je primenom različitih ...
Determination of the Coffin-Manson equation under low-cycle fatigue conditions
(Institut za ispitivanje materijala, Beograd, 2021)
The cycle loading of a material results in the modification of its properties and so in this paper is presented the behaviour of the fatigue life using low-cycle fatigue parameters. By applying the Coffin-Manson equation ...
Failure of steam line causes determined by NDT testing in power and heating plants
(Gruppo Italiano Frattura, 2013)
This paper examines leakage and damages of steam and provides an overview of NDT testing in order to determine the cause of steam lines failure in power plants and heating plants. This approach may be applied to similar ...
