Oznake: utrujanje;termično utrujanje;servohidravlični trgalni stroj s povratno zanko;preizkušanje s spektrom obremenitve;fatigue testing;thermal fatigue;closed loop servo hydraulic testing device;load spectrum simulation;
The paper presents the proposal of new design of closed loop servo hydraulic device for fatigue testing, induced by mechanical loading spectrum and variation of temperature. In addition to easier testing performance and more accurate results, the use of this solution offers significant saving in tes ...

Oznake: zvarni spoji;mikrostruktura;P91 jeklo;toplotno vplivano območje;toplotna obdelava;welded joints;microstructures;P91 steel;heat-affected zone;heat treatment;
In the process of testing real components exposed to elevated temperature, it is not possible to neglect cracks. The most significant cracks can be induced by welding, which is applied for joining of structural components. Pressure equipment in service is also exposed to high pressure and high stres ...

Suitability of heat treatment for crack resistance of material in the connection part of heavy transporter for liquid slag
Tomaž Vuherer, Ljubica Milović, Milorad Zrilić, Ivan Samardžić, Vladimir Gliha
Kratki znanstveni prispevek
Oznake: zvari;toplotna obdelava;zaostale napetosti;sprostitve napetosti;odpornost na razpoke;weld;heat treatment;residual stress;stress relaxation;crack resistance;
The post weld heat treatment (PWHT) was used to reduce the level of the residual stresses and increase of the crack resistance of the materal in the cnnection part. The article presents the results of the residual stress measurements immediately after welding and after the stress relaxation by the P ...

Determination of fatigue crack growth parameters in welded joint of HSLA steel
Ljubica Milović, Tomaž Vuherer, Zoran Radaković, Blagoj Petrovski, Miodrag D. Janković, Milorad Zrilić, Darko Daničić
Objavljeni znanstveni prispevek na konferenci
Oznake: HSLA jekla;rast razpoke;HSLA steel;crack growth rate;fatigue threshold;Paris' law;
The structural integrity and operational safety of welded pressure vessels primarily depends on the behaviour of weldments. In spite of all efforts in material production and improvements in welding techniques, including strict codes, requirements and directives, the crack occurrence in welded struc ...

Since additive technologies in dentistry are gradually replacing metal casting technology, it is necessary to evaluate new dental constructions intended for the development of removable partial denture frameworks. The aim of this research was to evaluate the microstructure and mechanical properties ...
