Validation of linear damage rules using random loading
Mitja Franko, Marko Sedlaček, Bojan Podgornik, Marko Nagode
Izvirni znanstveni članek
Oznake: damages;multiaxial;fatigue;critical plane;signed von Mises;
Fatigue damage is a parameter which plays an important role in lifetime and reliability predictions of randomly loaded structures. In this paper, four different forms of the Miner linear accumulation damage rule are examined. They are used to compare observed experimental damage and the results of n ...

Formation of laser-induced periodic surface structures (LIPSS) on tool steel by multiple picosecond laser pulses of different polarizations
Peter Gregorčič, Marko Sedlaček, Bojan Podgornik, Jürgen Reif
Izvirni znanstveni članek
Oznake: LIPSS;self-organization model;laser microprocessing;
Laser-induced periodic surface structures (LIPSS) are produced on cold work tool steel by irradiation with a low number of picosecond laser pulses. As expected, the ripples, with a period of about 90% of the laser wavelength, are oriented perpendicular to the laser polarization. Subsequent irradiati ...

Influence of austempering of as-cast medium carbon high-silicon steel on wear resistance
Marko Sedlaček, Grega Klančnik, Aleš Nagode, Jaka Burja
Izvirni znanstveni članek
Oznake: austempering wear;lower bainite;wear;impact toughness;hardness;
The aim of this study was to evaluate the effect of austempering compared to quenching and low-temperature tempering on wear resistance of an as-cast medium carbon high-silicon steel intended for rock breaking. Austempering was done by isothermal holding at 270, 300 and 350 °C in molten salt baths, ...

Tribological properties of solid solution strengthened laser cladded NiCrBSi/WC-12Co metal matrix composite coatings
Zoran Bergant, Barbara Šetina, Imre Felde, Roman Šturm, Marko Sedlaček
Izvirni znanstveni članek
Oznake: obraba;utrjevanje;lasersko obleganje;prevleke;wear;solid-solution strengthening;laser cladding;NiCrBSi;WC-Co;coating;
NiCrBSi, WC-12Co and NiCrBSi with 30, 40 and 50 wt.% WC-12Co coatings were produced on low carbon steel by laser cladding with an Nd:YAG laser with a multi-jet coaxial cladding-nozzle. The microstructure properties after WC-12Co alloying were investigated by scanning electron microscopy (SEM), energ ...
